Come onto your hands and knees with your shoulders directly over your wrists and your knees underneath your hips. Place the foam roller underneath both hands.
Lift your knees off the ground and extend your legs behind you so you're in a high plank position.
Hold this position for 30 seconds, maintaining a flat back and drawing the navel in toward your spine.
Complete three sets of 30-second holds followed by a 30- to 60-second rest.
