I had a friend on the school football team show me how to perform cleans and he didn't seem to know all those details I've read about like first-pull, second-pull. He did emphasize things like back straight, and hips low.
Since I don't plan on going to any olympic weightlifting competitions, it does it matter if I'm not using completely effective O-Lifting technique? I figure as long as I'm not injuring myself its alright. I just wanted an explosive and fun movement in my workouts, and cleans fit the bill.
