I actually try to do some calisthenics before I start work and make sure I drink lots of water. I will also do some pushups throughout the day to keep my blood flowing. But then again. I work from home and have that luxury. Suppose you can do some exercise in an office to if you got the right culture? Anyone else do exercise in the office? (Sans gym)
Just saw that this was commented as spam. Well, I wrote that post in hopes that others who want to break away from their desk jobs and start telecommuting could learn from my own experience.
