The Pilates Arc Barrel is lightweight, portable and has upholstered arches that help support the back and shoulders and open up the neck, hips and thighs. As we advance in age, the muscles weaken which causes our spine to lose its natural curve. The Pilates Arc Barrel strengthens the abdominal, back and shoulder muscles to keep the spine strong and supple. The chest opens up, shoulders straighten, and the hump back (if any) can disappear. An open chest facilitates easier and deeper breathing. The Pilates Arc Barrel is great rehabilitative tool for those recovering from stress, tension or injury and make a safe surface for deep stretching.
