Wow. I was on board with most you said until this. To assume that a given exercise is designed for one purpose is moronic. For example, squats can be used to give size, speed, or explosiveness depending on the purpose. Training for speed, endurance, or explosiveness has a whole hell of alot more to do with more olympic sports then power lifting. Only power lifters care about how much I can push up in one rep and no one else.
