I see a lot of young guys scrapping their work by doing unlimited set of curls or doing too much bench work without good form. I just need to go in my gym to see that.
I see a lot of young man succesfully doing powerlifting because they learn how to lift properly, and learn how to do it in a continuous curve. Just need to go in the high school gymnasium for after hour powerlifting.
For me learning how to lift big before doing some unlimited sets of bodybuilding program it's just sense.
Give your body a good foundation before trying fancy moves, for me it's more secure and less likely to be injured in the future.
