For quad activation should you aim to drive through the heel of the foot or the ball of the foot. Having trouble engaging my quads during my high bar back squats. Any help/tips to get my quads firing would be great!
I like using the front squat to pre fatigue also. You can also place a 2.5 lb plate under your heals yo elevate them and place more tension on the quads. I love doing goblet squats this way, quads are toast after those
