An excellent exercise to strengthen the stabilising muscles of the spine, lower back and buttocks.
Lying on your right side prop your self up on your right forearm. Your forearm should be under your shoulder and in line with your hips. Straighten your legs and place one foot on top of the other. Rest your left arm on your side.
Engage your abdominal muscles and push downwards through your right elbow to raise your hips off the ground. Making sure that you keep the ribcage elevated and shoulders in line with each other.
Hold the position for 8 seconds then return to the start, wait for 2 seconds before repeating.
Aim to complete 5-10 repetitions on your right side before swapping to the left.
