I wanted to point out one other interesting thing about Olympic high jumper Amy Acuff. She does no conventional weight training:
"I stopped all conventional weightlifting in December. People would think that's crazy, you have to do a bunch of squats and cleans right now, but I'm convinced it can be counterproductive."
Instead, she does Pilates:
"I find that the pilates training really gives me a lot of refinement and efficiency in my movement because at this point me being successful is not about me having the brute strength to be better than anyone. It's about training and utilizing all the stretch reflexes you can have in your body and maintaining strength and elasticity and power through a movement."
