In heel-up, power comes from the thigh muscles and the ball of the foot hits the pedal. In contrast, heel-down uses force from your ankles. You're able to use a lot more power with heel-up rather than heel-down. Both heel-up and heel-down are acceptable ways to pedal the bass drum, but HEEL-UP is more commonly used, especially in rock music.
