The 17 Muscles of the Shoulder Blade: Why Dynamic Glide Beats Heavy Weights

The most mobile & flexible joint in the body!

Unlike most joints, your shoulder blade has no direct bony connection to your rib cage. It connects to the rest of your skeleton through the collarbone, while a network of muscle supports and controls its movement. That’s what makes the shoulder blade so remarkable. It can glide, tilt and rotate as you move your arms — helping give your shoulders their extraordinary range of motion. But that freedom depends on coordinated movement. The muscles around the shoulder blade play a huge role in how our shoulders move, feel and function. ShoulderBack Pro is designed to help you explore that movement through simple, controlled routines: both arms working together, with you determining the effort and range.

A different kind of effort

With weights, you choose a load and gravity sets the direction of pull, so setup and technique matter depending on the exercise. With ShoulderBack Pro, your two halves set the effort, range, and direction in a cooperative "dance".

The assist-resist secret

With ShoulderBack Pro, both halves alternatley provide resistance / assistance. Very efficient and safe! You set the effort for the entire range. Because nothing can snap or drop, the body doesn't brace defensively — and all 17 muscles can get involved.

Within a short period, you begin to get that 'standing an inch taller' feeling.
