Don't know why you're getting downvotes, this is some "Brave New World" level BS- it's not enough to own your ass for 10-12 hours a day, now you have to spend another hour on a treadmill so they can get more out of you. Hope you're also spending a couple of hours on 'passion' projects to keep your skills sharp, and getting a full 8 hours of sleep as well. Unless you're getting paid like a pro athlete screw that.

It's ultimately your call as an employee if you want to work longer/harder/faster, but I don't think there's anything wrong with exercising and 'passion projects'.

I exercise twice weekly, and spend around 2 hours on my own projects - purely so I am stonger, both physically and mentally - which'll lead me to higher paying work in the future (not to mention I love my pet projects!).

My employers know that at 5:30, I down tools and under no circumstances, will respond to any calls/emails until 9am the following morning.

Do what you do for you, not for anyone else.
