it's not the game.. it's the prep and practice work. that may account for hundreds of reps.. and the torque on the hip and other fulcrums of force can be enormous.. you watch a guy like Hansen who literally corkscrews his body to whip his leg through the kick and I can see how a guy could easily tear something if he is just a little out of balance
