Workout while experiments

I usually enjoy workouts while performing experiments. When I should wait five minutes, I try to push-up by using a chair. My favorite exercise space is a dark room where I use for the detection of western blot signals. Because I am always alone in the room, I don't have to mind person's eyes. I perform push-up, knee bend and abdominal muscles exercise. I usually feel pain in my muscles due to these exercises when I perform experiments.
