This is the 4 point kneeling Superman exercise, and its aim is to strengthen your core muscles in your torso, improve spinal support, and increase glute strength.

Start on your hands and knees in a 4 point kneeling position on the floor. Aim to have your shoulders over your hands, and your hips over your knees, with your back in a stable and flat position.

From this position, whilst you keep your torso in a stable position, you want to take one arm forward at the same time you take your opposite leg backwards. So if you move your right arm forward, you will take your left leg backwards.
When you have your arms and legs out fully extended, you want to slowly return back to the start position.

Whilst doing this movement there are number of common faults people do. Make sure you keep your torso in a stable position without any arching or collapsing of the back, also try not to rotate your hips when extending the leg backwards. When moving the arms and legs, keep the movement slow and controlled, and avoid the temptation of moving quickly, this will increase the chances of your torso and hips not being as stable.

Finally, avoid lifting your head upwards when doing the movements as this will again cause your back to start arching, it should instead be in a neutral position as you look at the floor.

Aim to complete the reps and sets as suggested in your rehab programme.
