Start in a kneeling position with your hands under your shoulders, and knees under your hips.
Place a wobble cushion under the knee on your affected leg.
Bring your other leg forwards and place your foot flat on the floor.
Hold a weight in both hands and straighten your body up.
Maintaining your balance, bring your hands down towards your thigh on your kneeling leg.
Rotate the weight up and back, allowing your body to rotate with the movement.
