This device is a smaller version of our standard Middle Back Strengthener designed for children (ages 8-15 years old) and petite adults, specifically with a shoulder width measurement of 39 inches or less.
Like the Middle Back Strengthener, this Jr. version is two cushioned arm loops connected by a tough elastic band. The elastic band is the resistance against which the middle back muscles are worked. By using this device just two minutes a day, three times a week will slowly help to reverse bad posture and ease the strain on the muscles in the middle back and neck.
