Lie on your front with your hands by your shoulders and your elbows by your side.
Lift just your pelvis and move it towards the left, relax back down. Make sure the pelvis is the only part that moves. Press through the ground with your hands, arching your back so your chest comes off the floor.
Your lower body should remain in contact with the floor.
Hold for the required amount of time and then return to starting position.
Repeat on the right.
