Movement: Step forward onto your heel, keeping your knees in line with your toes and your hips level. Brace through your stomach and do not allow your lower back to round. Descend until just before your knee touches the floor, then - pressing your your heel and not the toes - step back to the start position. Perform the desired number of repetitions and repeat with your opposite leg.
Repetitions: Perform all prescribed reps on one side, then on the other. This counts as one set.
