Behind-Back Shoulder Stretch

Anterior shoulder mobility, chest opening, posture correction

Minimum Effective Dose
40s
The shortest time that still creates real, measurable change. Hit the dose and the benefit starts. Everything after is bonus.

Why it works

Desk work rounds the shoulders forward, shortening the front of the shoulder capsule. This stretch reverses that pattern by opening the anterior shoulder while keeping the ribs down, which prevents the common compensation of arching the lower back.

How to do it

Chest opens. Ribs stay down.
Feel the front shoulder lengthen, not the low back arching. Ribs down.

Variants

Easier
Hands wider.
Less stretch, more control. Ribs stay down.
Harder
Hands closer. Slow lift.
Feel the front of the shoulder open. Hold the top.
