Longbox Shoulder Stretch

Longbox Shoulder Stretch on Reformer: 30 Modifications for All Levels

Longbox Shoulder Stretch on Reformer is a wonderfully effective upper-body mobility exercise from the original Reformer Pilates Card Deck, which features 48 reformer exercises designed to build strength, control, flexibility, and better alignment.

This stretch targets the shoulders, lats, upper back, and the side body, while also encouraging a strong hip hinge. It’s especially helpful if you spend time at a desk, teach with your arms a lot, or feel tight through the upper back. The secret sauce is keeping the spine long and letting the pelvis glide back, rather than collapsing into the shoulders.

The setup is simple: stand with legs straight and feet wider than hip-width apart. Place hands on the longbox and stretch your pelvis backward. Bend down, keeping your forearms and hands on the box. Breathe into the ribcage and let the shoulders soften.
