Training Strategies

The role of stretching: what it does and doesn’t do

Stretching is often treated as a warm-up formality or a cool-down ritual—with little attention paid to the neurological and biomechanical nuances that distinguish one method from another. Stretching isn’t a one-size-fits-all practice. It’s a tool. And the way it’s applied should depend on the outcome you’re targeting—whether that’s joint integrity, end-range control, fascial tensioning, or recovery.

Body Mechanics

What is scapular winging, and how do we treat it?

Scapular winging occurs when the medial (inner edge) and inferior (bottom corner) aspects of the scapula (shoulder blade) lift away from the rib cage. This often becomes visible during scapular depression and retraction (pulling the shoulder blade down and towards the spine), but in many cases can also be seen at rest.

Body Mechanics

What is scapulo-humoral rhythm, and why does it matter

Scapulohumeral rhythm describes the coordinated movement between the shoulder blade (scapula) and the upper arm bone (humerus) during arm elevation, such as abduction. After the first ~30 degrees of humeral abduction (think of the early part of a lateral raise), the scapula begins to upwardly rotate in a consistent 2:1 ratio with the humerus — for every 2 degrees the humerus moves, the scapula rotates 1 degree.
