Movement: Step forward onto your heel, keeping your knee behind and 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. Keep your elbows straight and use the muscles of your core to maintain stability.
Repetitions: Perform all prescribed reps on one side, then on the other. This counts as one set.
