Lie with your arms out, palms up. Raise your legs until your feet are directly above your pelvis.

Keeping your head and upper back on the floor, slowly rotate your legs to the right as far as you can, holding your legs together. A slight bend in your knees is fine. Hold, rotate your legs back to the centre, then repeat to the left. Continue from side to side for as many repetitions as you can.

In between each rotation, try raising your backside off the ground and slowly twisting your hips to the left. Your legs should stay straight, with your feet pointing towards the ceiling. Pause, lower back down, twisting back into the starting position, then repeat to the right.
