Jon Call is a specialist in something he calls Acrobolix, a blend of strength training, stretching and aerial flips. To illustrate his power and flexibility in a single exercise, Call does an overhead press with a 100-pound barbell while lowering himself into splits with his feet on two chairs. It goes without saying, but here's our disclaimer anyway: Don't try this at home (or anywhere else for that matter). Leave it to the professionals like Call.
