Instructions
Lie face down on the ground with your legs together and your arms at your sides. Position your hands beneath your shoulders.
Tighten your core and elevate your upper body off the ground, stabilizing yourself with your forearms. Your feet, shins, and knees will remain on the ground.
Do not allow your hips to drop down. Hold the tension in your core for the prescribed amount of time. Slowly release back to the starting position.
