HOW: Start in the plank position with your elbows straight, hands slightly back from your shoulders, and your toes pushing into the ground. Lower your hips about an inch off the floor while your toes continue to push into the ground. While maintaining this arched back position, your body close to the ground and push back up.
FEEL: You should feel your triceps and core working. You should also feel a stretch in your low back.
COMPENSATION: Don’t let your hips rest on the ground, keep them elevated during the push up process. Make sure to start with your elbows straight, not bent. Look straight ahead instead of at the ground while performing the push up.
