Where do you "feel it" when you perform squats? If your answer doesn't include the entire thigh AND the glutes then you need some help w/ your form! Also, you should NEVER feel them in your knees. Use this drill to help. Face a wall w/ your toes touching. Crease through the front of your hips and let your pelvis travel far backwards. You should be able to at least go parallel, if not touch the ground without contacting the wall. Use this as a warm up or an exercise! Keep your weight on the heels to avoid falling back. I hope to be a "pain in your butt" w/ this posting!
