Edit: I just realized that not everyone does jumping burpees. If I cut out the jump and am careful to not flare my elbows, it might work. I'll give it a try after my wife wakes up.

I like burpees, but the ceiling is barely taller than a standard door frame. Also, I think it would be very careful to come down and not flare my elbows wider than 2 feet. The bathroom is so small that they use a mini square sink, maybe 10 inch diagonal. Maybe I could kick my feet out of the shower and next to the toilet, but that still wouldn't solve the ceiling height issue, and I'd probably eventually injure myself by accidentally kicking the toilet.

On a side note, I have a buddy who was using burpees for Tabata training in his kitchen. His wife complained about the sweat on the floor, so he did them on a towel. He stopped doing Tabata when his towel slipped and he hit his chin hard on the tile.
