Side plank

The side plank challenges your stability and improves core strength by working the muscles along the side of your body:

• Lie on your left side, raising yourself onto your left forearm (top illustration). Place your left shoulder directly above your left elbow, keeping your shoulders, hips and knees in a straight line. Rest your right arm along the side of your body.
• Tighten the abdominal muscles. Hold for three deep breaths. Repeat on your right side.
• For added challenge, balance on your left hand. Raise your hips off the floor and extend your right hand toward the ceiling (bottom illustration). Hold for three deep breaths. Repeat on your right side.
