Standing tall with feet hip width apart. Place a secure chair or bench roughly 30cm directly behind you. Extend both arms out in front as counter-balance as you lift your left foot off the ground and hinge at your hips and soften your right knee. Slowly lower your bum towards the chair. As soon as you make contact with the chair drive off your right heel and return to the start position. Perform the remaining reps on the right leg before swapping to the left.
