Get ready to engage your arms, shoulders, and the entire backside of your body with this exercise!
Lie facedown with your legs extended hip-width apart, toes pointed on the floor, and arms extended overhead (palms pressed into the plates). Extend your spine, and as you lift your chest, slide your arms out to the sides and then bend them into your body, tracing a circle on the floor. Slide your arms back out in front of you as you lower your chest. That's one rep. Do 15 reps total.
Tip: Look down at the floor, keeping your chin tucked in towards your chest, to avoid neck strain during this move.
