I’ve been doing this thing at work for the last few weeks. Whenever I have to go use the restroom, I first pop into an infrequently used conference room and do some calesthenics. Nothing extraordinary, mind you. I usually pick three exercises from a list that includes sit ups, push ups, squats, side leg lifts, back leg lifts, and planks. It’s really probably only about 60 seconds of exercise at a time, but it has a noticable effect (affect? Fuck, I can never get that one right) on my heartrate and makes me feel all good. Plus, as a reward, I get to pee at the end. Not in the conference room, mind you.
