I love this post. As a hacker myself I can relate. I did not do much while at school - that pretty much took all my time. Also, "regular" sports did not appeal to me. I started taking up martial arts as soon as I started working and it has completely changed my life. It clears my head, keeps me fit.
I never liked the idea of hitting the gym just so you could have a "beach body". The idea of learning a new skill (or set of skills in my case) appealed to me. Having a fit and healthy body was a side effect. The inverse wasn't true, - lifting weights at the gym wouldn't yield any additional skill so it definitely did not appeal to me.
I guess what I'm trying to say is that if you find the physical equivalent to hacking - whether it's rock climbing, free running, or doing wushu - it's fun and will also keep you in shape.
Going to the gym does give you some incredible new skills, though, just not in the way you would think. How useful is it to be able to properly pick up very heavy objects, or to be able to outrun 70% of the population? What about the benefit of being more attractive, which does lead itself to more opportunities?
You're definitely right about choosing your own path, though -- as long as you do something to stay in shape, you'll be alright. Any sport can bring useful new skills to the table.
I love exercising, particularly weight training, and do it daily. I stopped for about a year, but now that I've developed the habit again I remember how amazing it is to just... feel good about my body and my health. I wouldn't trade it for anything.
Ditto... I'm on a break at the moment because my house is too far from the gym and I don't want to risk being flattened by an angry bus or cab by biking to it every day - and, perhaps more importantly, I'm too lazy to go out much in the cold and wet London winter.
But I'm planning to move soon, and one of my first priorities while moving will be to find a place close to a gym so I can start weight-lifting again. It does feel absolutely great, and the article is right - it's a scientific/experimentation endeavour. It took me 2 years to figure out how to make my body actually build muscle.
For the record, it turned out to be a combination of the following (and all these ducks needed to be lined up, which is why it took me so long to figure out the winning combination):
- Rely primarily on heavy Squats and Partial Deadlifts (which have to be done very carefully following good form to avoid injury - see http://www.amazon.com/Insiders-Tell-All-Handbook-Weight-Trai... for information) as my core exercises... if I don't do these two, the other weight lifting exercises don't build much muscle for me.
- Over-eat and particularly eat some protein shakes while training (need to ensure there's an abundance of foodstuff for my body to build new muscle)
- Make sure I get at least 8, ideally 9 hours of sleep every night - sleep deprivation == no new muscle tissue
- Train each major muscle group only 1.5 times a week - i.e. 3 times every 2 weeks. More often than that is actually counter-productive.
The benefit of doing all this is feeling fit, feeling great, feeling on top of things. I strongly recommend it to anyone (just make sure you follow safe exercise form - and don't necessarily trust the gym staff about that, I've seen many of them practice or even advise very poor exercise form that will cause injuries in the next 10-20 years).
Training muscle more often will not hurt you, in fact I have had some of my best results training more frequently then "3 times every 2 weeks"
Studies have shown protein biosynthesis drops to about 0 approx 48 hours (or less) following the workout. Muscle development cannot occur without protein synthesis (it is muscle development). Commonly you see pro bodybuilder and the such claiming to only exercise muscle groups once per week... which is fine, when you are on anabolics you are in a constant state of protein synthesis.
On a side note, NSAI drugs like Tylenol, asprin, naprox... Will all impede protein synthesis as well, making it almost impossible.
I agree, most gym staff doesn't know what they are talking about... In fact when it comes to exercise very few people seem to have a clue. Most people simply believe the same junk put in magazines and websites with no scientific basis.
Well, people who do splits are training each muscle multiple times per week. If you have an "arms day" and a "chest day" then you're hitting your triceps twice, for example. On "legs day" you're working your abs as well as your quads to squat, even if you have another abs workout another day.
I think cycling in London is not as dangerous or scary as people generally like to believe by default. You can avoid most of the traffic by following cycling routes. Transport for London publishes quite good cycling maps -http://www.tfl.gov.uk/roadusers/cycling/8966.aspx
I was lazy about cycling for a long time for the same reasons you mention. But now I find that cycling is actually a great way to beat the cold.
And the rain? Well, you just get used to it...
Slowly wheeling around small lanes is also good thinking time, especially at the end of the day.
I have never cycled in London, but I'd imagine it is similar to the US. There is no need to be excessively afraid of cabs and busses -- if those people hit you, their life is ruined. (Don't take this as an invitation to drive stupidly, though. Stay predictable.)
It's the dumbasses from the suburbs that I find to be the problem. They have never seen anyone riding a bike before, so they don't know how to act properly. If I had a nickel for every time I was almost hit from behind by someone with non-Chicago stickers... (Hint to these people: if there are 3 lanes, you don't have to drive so close to the right side that you clip the mirrors off parked cars.)
I was living up in Stoke Newington when I was in London (N16 7AJ repreSENT!), and that's under 10 minutes to the Lea River and Regent's Canal, both of which are fantastic cycling routes. The Grand Union is also delightful, especially with Little Venice right after Paddington basin.
I'll admit, though, that my commute was pretty easy, just straight on the A10 through Shoreditch/Dalston. If you see yourself using a bike to shuttle to mass transit, get a folding bike, they're awfully convenient; if you see yourself using a bike as a main means of transit, stay with a full-size city bike.
I've found the same thing; numerous factors go into muscle gain. For me, I no longer eat as much or as balanced as I did when I was training seriously, which means I don't make the gains I used to. I also lack a partner which means no spotter; I think spotting is a huge help. I'll be surprised if I am back to my old level even within 6 months, which is a really long time just to double the weight I can put up in most exercises.
But you know what? I don't really care. Just the act of going, of noticing slightly flabby parts of me start to iron out after only a month... I'm pretty happy with it. It still makes me sigh, though, when I can't even bench 145.
i'm a personal trainer, and that is the most succinct and accurate description of the fundamentals of strength training that i have ever read, all the way down to the comment about gym staffers who often don't know what they're talking about. +1. now get back in the gym!
Have you considered calisthenics? (I think it's called something else outside the US.)
I've been interested in this book, I prefer the idea of using your own body weight. And I don't like the idea of going to the gym by myself. I'm not interested in looking like a bodybuilder, with everyone being overweight simply being fit is quite enough.
One trick I found to get myself to the gym was to pick a TV show I liked (Doctor Who or whatever floats your boat) where I was several seasons behind, and I would ONLY watch that show on my iPhone while at the gym doing cardio.
Obviously when you move to the weight machines you can't keep watching the show, but it solved several problems for me:
1) It kept me from getting bored while doing cardio, which is a big issue for me.
2) It made me push for a 40 minute session doing cardio, so I could finish the episode.
3) It made me MUCH more likely to come to the gym the next day, because I wanted to see what happened next (it's good to pick a show with long story arc and end-of-episode cliff-hangers).
Me too. Except I stopped for about 2 years, and haven't gotten back into it yet. The gym is still collecting my membership fees every month. I should go back just to spite them.
I got my membership here in September of last year and didn't start going daily until January 1st (I made it a resolution). In my experience, I either go 6 days a week or I go 0. It takes a ton of reinforcement for me to make the habit.
For programmers in colder climates and without gym memberships: don't underestimate the value of shopping centers. They're large, climate controlled, and a godsend when the wind chill drops to -40.
I've surprised myself by enjoying ice skating out doors with my kids. Something I did about once a year before this year, in which we've gone about 5 times. Not enough times to get/stay in shape, obviously, but it felt like a good workout and not that hard to stay warm if you keep moving.
To add to that here are a couple things I've done to stay active in non-traditional ways:
Rock/Tree climbing (With a harness and proper training)
Paintball/Airsoft -If you can play someplace with no field fee so you can spend a couple hours at it, it can be a good cardio workout. It is also very much a tactical/thinking activity so it engages your brain.
In my experience, going to a traditional gym to lift weights or run on a treadmill is very boring. I never was able to maintain a traditional exercise program like that for any length of time. However, I have recently found the secret to getting addicted to exercising: sports.
I fell in love with rock climbing about a year ago and feel the need to go at least three times a week. I would go more often, but I am usually too sore from the intense work out. Climbing creates a physical and emotional high that is unmatched by anything I have ever experienced.
I lifted weights in college, but never achieved the muscular definition and level of fitness that I have achieved through rock climbing. It helps create a balance of strength, endurance, and flexibility throughout the entire body. With weight lifting, I could never acquire the discipline to strive for the next weight increment. But with rock climbing, I yearn to be able to complete the next route and am singularly focused on reaching that goal.
It also helps that rock climbing can sometimes be a more social activity that weight lifting.
We need to start a hacker health site. Hackers know that there is the way everybody does it, and then there is the less obvious, simpler and infinitely cooler way to approach it. The same has got to be true for fitness. I for one hate the idea of driving to a gym to stand next to a bunch of sweaty guys who look like they actually belong there for an hour 6 days a week. There has to be other, more fun way of getting in shape and eating right that will work better in the hacker lifestyle.
Apparently John Walker (co-founder of Autodesk) wrote a book on weight loss taking an engineering approach (The Hacker's Diet, http://www.fourmilab.ch/hackdiet/www/hackdiet.html). I wonder if anything like that has been written for strength training?
The 100 push-ups plan seemed to appeal especially to hackers, but while it seems like a good start it would be nice if it were a bit broader in scope.
An old parkour friend of mine started doing 10 pushups on the hour every hour he was awake. Then after a week, he would move up to 11, 12, etc. When he got to 25, he started over with inclined pushups. If you're into rock climbing, you could instead switch to tri-pushups or fingertips. It makes for a really good break from whatever you're working on during the day.
I could never quite get on it due to my classload, but he does probably 100 handstand pushups a day.
Researchers discovered that 7-OXO does not convert to testosterone or estrogen, minimizing androgenic activity, and supports various physiological processes. It is several times more potent than DHEA in stimulating the thermogenic enzymes of the liver, promotes basal metabolism, and helps to increase the lean/adipose ratio.
This seems really interesting--- bizarre that there isn't more research on it. I've also had AMAZING success with Provigil (import from India el-cheapo). It keeps me in the zone for hours on end... with no side effects except for a welcomed slight loss of appetite. I wouldn't have believed you if you told me a drug like it exists, but sure enough...
It's almost like the FDA is plotting against us...
bizarre that there isn't more research on [7-Keto].
Check my PubMed links, in my response to shaunxcode.
Provigil (import from India el-cheapo).
I have imported the older, cheaper version of Provigil (Adrafinil; costs about 1/5th of Provigil price, after correcting for dose-equivalence). I have been wanting to try Provigil (also known as Modafinil). Which offshore pharmacy do you use, if you don't mind my asking?
I've used shop.airsealed.com but more recently www.thepharmacyexpress.com because it's cheaper-- Never had any problems.
I love pharma-hacking, always looking for recommendations... India is the way to go. I was over there a couple years ago and someone told me they basically only have two price points for pills in the country-- either ~13 cents or ~24 cents. Totally different pricing dynamics without all those nasty patent laws... One time I asked a hotel concierge for a substantial supply of Ambien and he just laughed, "no valium? ketamine?"
When I was looking into getting cheap Adderal online after losing my insurance, several of the sites I researched were exposed as selling fake meds, so I gave up. How are you sure that you are getting the actual medication?
When I was looking into getting cheap Adderal online after losing my insurance, several of the sites I researched were exposed as selling fake meds
One clue should have been the fact that they were claiming to be selling Adderall. Adderall is a Schedule II drug. http://en.wikipedia.org/wiki/Adderall
We are not talking about trying to import things - like cocaine, morphine, Adderall and any other Schedule II drug - that cannot be legally imported. We are talking about normal, legally-importable drugs such as Provigil.
Looks like you need a license to import Modafinil into Canada, and can't get it without a prescription. (Schedule F Part 1). Can anyone that knows how these laws work confirm that?
Well I took a chance and it worked out alright, but it could be more difficult depending on the med... There is so much spam in the online pharmacy space you do have to cut through the clutter... I waded through as many forums and blog posts as possible to narrow my list down, then just started with a small order to see what would happen. Then as long as you get them and they look legit you will probably be okay. Also, find a place that will accept a credit cards... I've noticed legit places are really responsive in order to avoid charge backs.
RX-Mex (4rx) is good for other items. These are the lowest-price pharmacies, that are reliable and easy to deal with, I know of. (Some people complain about 4rx mass-emails. I haven't had any problems.)
What are the downsides to this stuff? I googled a bit and couldn't find anything particularly detrimental. It even seems have "memory enhancement" attributed to it.
http://www.delano.com/Articles/ketoDHEA.html - this was the most informative page that I could find discussing the benefits and claims against it. Seems to come out on top as being safe and effective though.
I don't know of any downsides to 7-Keto (7-oxo). However, I know that DHEA, on the other hand, has many downsides. It is important to note that 7-Keto (7-oxo) is not DHEA. It is a metabolite of DHEA. For a complete list of studies and abstracts, including the latest, I would search PubMed: http://www.ncbi.nlm.nih.gov/sites/entrez?db=pubmed&term=... (7-Keto search; 14 hits.)
Scientists have documented DHEA’s wide-ranging benefits in numerous clinical studies. DHEA helps to retard the effects of aging and promotes enhanced longevity, exerting a multitude of effects through its conversion to some 150 metabolites, each with unique actions within the body.
One of the most important of these is 7-Keto DHEA (commonly referred to as 7-Keto), a hormone metabolite that can safely boost immune function and help reduce body fat. Unlike DHEA, however, 7-Keto does not convert to estrogen and testosterone. Because DHEA and 7-Keto have separate and unique functions and properties, it is important to understand the differences between these two popular dietary supplements. [...]
A study with mice suggests that 7-Keto can boost memory as well.17 In this experiment, researchers at the University of Wisconsin in Madison trained young mice in the use of a water maze. They found that a single injection of 7-Keto (at 24 mg/kg of body weight) reversed experimentally induced memory loss. The scientists then fed 7-Keto or DHEA to old mice that had learned the maze. They discovered that memory of the water-maze training was retained during a four-week test period in the mice receiving 7-Keto but not in those treated with DHEA.
This study tested the hypothesis that 3-acetyl-7-oxo-dehydroepiandrosterone alone (7-Keto) and in combination with calcium citrate, green tea extract, ascorbic acid, chromium nicotinate and cholecalciferol (HUM5007) will increase the resting metabolic rate (RMR) of overweight subjects maintained on a calorie-restricted diet. [...]
In this study, the administration of HUM5007 or 7-Keto reversed the decrease in RMR normally associated with dieting. HUM5007 and 7-Keto increased RMR above basal levels and may benefit obese individuals with impaired energy expenditure. HUM5007 and 7-Keto were generally well tolerated and no serious adverse events were reported.
Note that it says, "7-Keto [was] generally well tolerated and no serious adverse events were reported". Cholecalciferol is also known as Vitamin D3 and is widely available as a dietary supplement.
I can't agree with this more. I despised gym and sports in high school, but in college I gradually took on more physical activity through a bit of martial arts (I was still a total slacker when it came to showing up for training, but it was better than before...) and I really think there's something that all intellectuals can learn through the concentration and coordination required from some sort of intense physical exercise. It's just my theory, but I think that part of the problem for "hackers" is that we tend to have eclectic tastes and conventional sports don't always appeal to us. So, if you don't like the normal sports of baseball, football, etc., seek out something different that's still good exercise. Try ultimate frisbee, or kendo, or rock climbing. You're bound to like something.
In my case it was a combination of factors, including a doctor advising I urgently make lifestyle changes to avoid premature death. Because nothing concentrates the mind like a well-written bug report with Issue: Programmer Dies flagged at the top.
The actual changes turned out to be fairly simple. I bike daily now, pay a bit more attention to what I eat, and have 45 minutes chiseled out to exercise approximately twice a week. (I really wish I had discovered the Hacker's Diet about, oh, 16 years ago would have been great.) I've never felt healthier, never had objectively better readings on my annual physical, and my personal Trac shows Bug #666 closed.
(Although I'll confess I have Feature Request: Abs still pending.)
For me, it was basically a question of "what is the simplest thing that could possibly work?". I started with just taking a quick lunch and then going for a walk, then I added some running around the block near where I live, and finally I added in some basic body-weight exercises (push-ups, sit-ups, etc).
For those who aren't sure of how to spend their gym time most efficiently, and get bored of doing the same old bike/treadmill routine, should check out CrossFit.
A workout is posted every day which is designed to deliver "a fitness that is, by design, broad, general, and inclusive". You can scale the workout to your own abilities and feel encouraged by the knowledge of thousands of others putting themselves through the same pain around the world.
CrossFit would be good enough on its own - having world experts design your training program takes the guesswork out of what to do - but it's the community that makes it special. You've got world class athletes and beginners having interesting and informed discussions on fitness and nutrition.
Take five minutes and see what you think. I've been a convert for two years and it beats all my previous training experience for getting fit and feeling healthy.
I hate exercising. I've always been in good shape, and I've never had to have any kind of exercise regime. But that's changing as I get older. Now I've tried exercising in several different ways, each time giving it a good solid month to get used to it, and I hate it.
Now I've started using the Hacker Diet method of general fitness, and I'm finding it simple, efficient, and unobstrusive. And I feel better. I've also started on the diet itself and I'm losing weight. At 5'10" and 175 pounds I'm targetting losing 35 pounds in the next 6 to 12 months. I've only just started, but I'm on track, and so far it's not a problem.
The Hacker Diet (and exercise) seems to suit me. The gym definitely doesn't, and I'm deeply suspicious of any drugs or supplements.
"Even if you're resolute in believing you won't feel one whit better from exercising, you'll certainly concede that you'll feel a whole lot worse after collapsing to the floor with a coronary. I've no direct experience with this particular unpleasantness from life's menu of surprises, but folks I've talked to who have are unanimous that it's best avoided. Those who dropped dead right away were unavailable for comment."
"The marvelous mechanism that is your body has many signals to let you know when problems arise. If you're exercising and you encounter chest pains, shortness of breath, or other indications that something is awry inside your rib cage, don't ignore them! ... Ignoring these signals from your body is the height of folly. It can lead to all kinds of tedious and exasperating side effects such as sudden death. "
Going to the gym after work Monday through Thursday improves my state of mind for the next working day. I've found that it has a huge bearing on my eating habits on those days, and my sleeping habits in general. I eat better and sleep less.
After losing the weight and getting in shape, my asthma and allergies disappeared, along with my eczema. Fitness has become one of the most important things in my life.
If there is one piece of advice I can give to anyone looking to get in shape it would be this: Stick with it and stay consistent. Fitness is a lifestyle, not a goal or destination (that's why diets fail).
I changed my lifestyle by introducing fitness and health about 2 years ago. I suffered from really bad migraines at least once a month. Now I get them about once a year if at all.
I went on a health kick for several months a couple of years ago. Went to the gym three times a week for an hour a shot. Did I feel better and was I more productive? Not really. At least, I didn't feel it except for about twenty minutes after the exercise. The exercise itself felt horrid, even after a few months.. and we're only talking running on a treadmill here.
So, like a lot of gym-goers, I stopped going, I've put on a few pounds back to my seemingly "natural" weight, and I'm sitting right here for now. I'm not sure organized exercise is for everyone, just like TDD or vegetarianism isn't for everyone either. Instead, I just eat reasonably (junk food at most two or three times a month, lots of veggies), make sure I don't sit down for a whole eight hours a day, and that seems to work for me even if I'm a bit squishy around the edges.
Exercise doesn't always have to be straight body building. I go rock climbing 2-3 times a week and I absolutely love it. One of the very few hobbies I kept up for well over a year (so far). On my off days, I run and sometimes supplement in the gym.
One caution for people hoping to start exercising and go from picture A to picture B: if you want to lose weight, exercise is not enough. You need to keep track of your calorie consumption, or you will just end up eating more. At least that was my experience. Restricting calories, on the other hand, works with or without exercise. Not that I'm advocating non-exercise.
I used to exercise a lot in high school but since college I've been doing less and less. Still, I seem to be unable to gain weight, its been like this my whole life, and it doesn't seem to matter what my diet is and how much I eat. My excuse for not exercising is that I would be even skinnier then I already am :)
are you strong and fit enough?
A few thoughts:
* Can you run a short distance without collapsing?
* If you're helping a buddy move furniture - are you able to take the heavy end?
* If the lift goes out - can you walk up a few flights of stairs without too much effort?
* Can you play backyard sport well?
Not everyone wants to be a bodybuilder, and you're probably better off than a lot of overweight hackers, but there's something to be said for being fit.
Two main reasons why working is important to programmers in particular:
1.) In general, programming is a well paid, lucrative profession. It takes a long time to learn how to program well, so naturally the rewards are large. However, these rewards really don't mean all that much if you aren't in a position to enjoy them. Becoming a millionaire before you are 40 is cool and all, but most people would rather have a long lifespan full of good health.
2.) Programming naturally leads to a large amount of time sitting down in front of a screen. It is also a pretty high stress job, which often results in excessive use of caffeine or other stimulants. Both of these habits are draining and unhealthy. In the long run they are bad news.
My biggest challenge when working out is the mental focus required. It takes a lot of energy to manage your sleep and eating schedules to the necessary degree. Also, there is a lot of background knowledge and thinking involved in planning proper work out plans. Bottom line is that as a Computer Science student, I work on things that require a large amount of mental focus every day. Adding another item to the list is of course difficult.
Having been in excellent shape only a year or two ago (I was a competitive swimmer in high school), I can say with full confidence that being in shape has a huge impact on how you run the rest of your life. I found that I was able to accomplish much more with my time and take on larger loads because of the discipline I learned through being an athlete. There's no question in my mind that staying in shape is worth it, but the difficulty in doing so should not be ignored. I am still struggling to adjust to the demands of a Computer Science education. In high school swimming competitively pretty much meant working out 4 to 5 hours a day all total. That's simply impossible in college when studying any type of Engineering or Science. I'm sure it's also impossible for a founder/working professional as well. Instead I'm trying to figure out how much I can accomplish with only an hour a day. With proper dieting habits, I'm convinced the hour will be enough, but it is a challenge. It will be worth it, but it's not easy!
Friends I've talked to who also struggle with these types of issues talk about how they don't have time. Obviously I understand that, and I'm sure most readers of news.YC can relate :-). Ultimately though one hour a day is a small price to pay. Mentally programmers are capable of doing some pretty crazy things. Anyone who's done an all night coding marathon to finish a project on time knows what I'm talking about. Getting in shape is simply a matter of redirecting that mental energy towards a different cause.
EDIT: Something I forgot to add. Another big barrier that people face is an aversion to going to the gym, where there are people who are in really good shape. It certainly can be intimidating, but have faith in the fact that your body is biologically designed to respond to regular and difficult work outs. The difference between you and the guy next to you bench pressing twice your body weight is a lot smaller than you think.
I particularly agree with your point about caffeine and stimulants. I've found that I very rarely do my best work when I'm all hyped up. Yes, sometimes you have to stay up to finish that last really cool feature or whatever... but most of the time when I go too long I just end up writing bad code that needs to be rewritten the next day anyways.
Speaking as a fat guy who's slowly getting back into shape (after taking 2 years off and gaining a bunch of weight), I liked the article -- everything except for the picture at the end.
People, probably for a good reason, have negative feelings associated with guys/girls who spend a huge amount of time at the gym. The word narcissistic comes to mind, also vanity. I'm not saying the writer is vain, just that a bodybuilding shot can be a little put-offish to some.
But more to the point, it emphasizes this huge gulf between the totally out of shape and the totally in-shape. The thing to focus on isn't the body building contests (if you like that sort of thing, which I don't), but it's his description of the day-to-day dedication it takes to make it work. If you want to lose a thousand pounds or run a marathon or whatever, those are great goals. Forget about them for now. For somebody who hasn't done it before, an even greater goal is to get out of bed tomorrow morning and go to the gym -- even if you don't exercise more than 5 minutes. Then do that again. And again and again.
Later on you lose the 40 pounds and start weight-lifting, as he did. Or maybe you go into flexibility training, or endurance training. Then even later you run the marathon, do the body-building show, etc.
Don't try to stick all of that in your head at one time. To a great degree, this is all about doing the same little things each day over and over again. It's not about the big things. Heck, you might not even want to do any of the competition stuff. Functional health -- being able to get around easily, climb stairs, lift heavy boxes, run for a departing plane, go for a 10-mile day hike -- that's a huge thing in itself. It doesn't have to be Twinkies or the Boston Marathon. There's lots of room in-between.
I spent $200 US on a cross trainer last year - best $200 I have ever spent.
I highly recommend one, you do not really feel how much of a workout you are getting until you stop, and it is also gentle - I have yet to experience soreness or injury.
No gym fees, no time spent going there and coming back, no having to deal with people, it works great . . . win win all around for me.
I never liked the idea of hitting the gym just so you could have a "beach body". The idea of learning a new skill (or set of skills in my case) appealed to me. Having a fit and healthy body was a side effect. The inverse wasn't true, - lifting weights at the gym wouldn't yield any additional skill so it definitely did not appeal to me.
I guess what I'm trying to say is that if you find the physical equivalent to hacking - whether it's rock climbing, free running, or doing wushu - it's fun and will also keep you in shape.
