Lie on your side with your upper body supported on your elbow.
Your hips should be straight with the knee of the lower leg bent to 90 degrees and the other knee straight.
Lift your hips off the floor until your sides are equal length.
Holding this position, lift your upper most leg directly up towards the ceiling and press your lower knee against the floor to lift you hips further upwards.
Hold this position for a moment.
Control the movement as you return to the starting position.
