Lie on your front with your hand under your shoulder and your forearm on a yoga block.
Tighten your abdominal and buttock muscles as you push yourself up through your arms, keeping your body straight.
You should have a straight line from your shoulders to your heels.
Maintaining this rigid position with your body, bend your elbows, keeping your gaze between your hands.
Your elbows should remain close in beside your body.
Push back through the floor to straighten your elbows out again.
Ensure you do not allow your hips or abdomen to sag.
