I was at our explorer academy (I know it was a while ago) but anways, they had a work out there called the "zoo" the explorers all got together in a circle and we had to do the bear walk, crab walk, the ostrage( jumping around the circle), mud puppy (basicly the army crawl w/o your legs). It was crazy workout it hurt like hell and you couldn't even move after that, then they made us march.
