Back squats are for back not legs because they have the word "back" in them...
I am going to tell my wife that "internet porn" is mostly about the "internet" and see how far I get!
"You just donít need to do squats to build muscular, strong legs. Focusing on things like leg presses, leg extension and lunges is a far more effective way to build great legs. "
Haha, because, knee injuries are 100% impossible with THESE moves!
