Stand in front of a Smith machine with one foot positioned slightly forward and the other foot back. Lower your body by bending the front knee and dropping your back knee toward the ground, keeping your torso upright and core engaged. Push through the front heel to return to the starting position. Perform the movement with controlled form to build lower-body strength and balance.
