Front Squats are an awesome quad exercise! In fact, I feel them more in my quads, than regular squats. I would start with just the bar to perfect your form. Set the bar a notch below where you would normally place it for regular squats. This will allow you to get under the bar more comfortably. The bar should rest between your front delts and upper pecs, it should NOT choke you. I do these rock bottom, and I can actually front squat about 85% of the weight I usually squat. Keep your elbows up high and chin up as well. A weight belt usually comes in handy, and you wanna keep your body as upright as possible. It's harder to cheat on these, and there's alot less stress on your lower back than regular squats. hope this helps, tell me how you like em!
