How far down should you go when you squat? I'm six feet tall, and when I squat, my butt is around 9 to 12 inches from the ground. A old, experience bodybuilder came to me and told me that I should only go half way down. He said that I'm going to mess up my knees and regret it when I get older. I followed his advice and I feel like I'm hitting more of my quads than my glutes. I rather have my quads grow than my glutes. However, I have a passion for martial arts, I train in it, and prefer performance over looks. So how far should you go down when doing squats?
