Place a BOSU ball on the floor on the flat side.
Step up onto the BOSU, standing on the soft side with your feet hips width apart and toes pointing forwards.
Tightening your abdominal muscles and keeping your back straight, bend your knees lowering down into a squat.
Ensure your knees travel directly forwards over your outer toes.
Keep your gaze ahead.
Control the movement as you straighten back up again.
