For health, gym at 5:30am 4 days during the work week and an occasional Saturday workout. I try to eat healthy but not to the point where I'm not looking forward to a meal. Cooking for my SO is also a big stress reliever after a long day or if she's about to start a 24 hour call shift or something.
Productivity wise, I'm personally a fan of the "Nike" approach: just do it. If you're at work, do work. Don't sit on HN or Reddit or Facebook. If you need to use RescueTime or change your hosts file or whatever, fine. But just doing what you're supposed to be doing when you're supposed to be doing it is about as crucial a piece of the puzzle to your success as you'll ever find.
