The hack squat calf raise is a compound exercise that targets both the quadriceps and the calves. By performing a calf raise at the end of a hack squat, you engage your lower leg muscles for an added challenge. This exercise is excellent for building lower body strength and improving balance.

1. Position yourself on the hack squat machine with your shoulders under the pads and feet shoulder-width apart.
2. Lower your body by bending your knees and hips, keeping your back straight and core engaged.
3. Once your thighs are parallel to the floor, pause briefly.
4. Push through your heels to return to the starting position.
5. At the top of the movement, rise onto your toes to perform a calf raise.
6. Hold the calf raise for a moment before lowering your heels back down.
7. Repeat the sequence for the desired number of repetitions.
