Zen Habits has a post on Minimalist Fitness: How to Get In Lean Shape With Little or No Equipment.  About ten years ago I was stuck in Ghana with a lot of free time on my hands.  I decided to put some effort into getting into shape with no equipment.  Sadly, I knew little to nothing about exercise, so I didn’t manage to come up with a routine anywhere as nice as this one. 

My routine as I recall it involved jumping rope for 15-20 minutes, pushups, and trying to bench press my bed.  It wasn’t a great full body workout, but it was better than nothing.  One morning I tried to bench press my bed and it fell apart on me.  After I reassembled it, I quit that part of the routine. 

I don’t think I could follow Zen Habit’s exercises as a number of them involve a chin-up bar which I don’t have or involve jumping.  The room I exercise in has a sixish foot ceiling, so I don’t think jumping would be too good for my mental health.
