an Indian run was fun too, during wrestling practice, we would all lay on the ground in a huge circle, pounding the ground, and when coach blew the whistle, one of us would get up, run around the circle, and then drop down. Then the next person would go, and so on and so forth.
another interesting workout I learned in wrestling were called "Burn-outs" this was a combination of a jumping jack, push-up, and a squat thrust/burpee. We'd start with one, then two, and so on...I think the most we've ever gone up to was 150...and then...here's the fun part...you work your way back down to one.
