Wolf, this is normal if your form is good. The usual form of the squat does not hit the quads primarily (especially in taller people). Say this to yourself 1254 times a day to overcome the Weider-induced trance you have been in! Okay, so if you want to develop your quads and you like squats, here are some suggestions: 1. Try King squats. Get the video and learn a new technique. 2. Go all the way down. 3. Try 1-and-1/3 squats. 4. Do leg extensions before you squat as a pre-exhaustion technique to focus on the quads. 5. Experiment with different foot/bar placements. If the people who were critiquing you were powerlifters, they probably told you that your form was excellent if you had a wide stance and the bar was halfway down your back. Try having the bar higher up on your back, elevating your heels, staying more upright during ascent and using a narrower stance. These techniques will all move the more of the effort to your quads and less to your posterior chain.
