Supine Floor Angel
3 × 10 reps
Supine snow-angel arm slide that exposes shoulder flexion and external-rotation range while the floor supports the thoracic spine.
How to do it
- Lie on your back with the arms in a comfortable goalpost position.
- Slide the arms overhead while maintaining only comfortable forearm and hand contact.
- Return to the starting position without forcing the wrists down or arching the lower back.
- Repeat slowly and controlled.
Form cues
- Control the ribs without forcefully flattening the lower back.
- Use a comfortable elbow angle; full floor contact is not required.
- Stop for front-of-shoulder pain, numbness or tingling.
Why this exercise helps
Tracing a snow-angel arc while lying down reduces the balance and trunk-control demands of an upright shoulder exercise. The floor provides feedback about the arm path and how much range is comfortable without needing every part of the arm to remain in contact. Differences in contact can reflect anatomy, current mobility, comfort, or the chosen rib and trunk position; the drill cannot identify one restricted muscle. Moving slowly also lets the shoulder blades accompany the arms as they travel overhead.
Stop or modify if
- Forcing the wrists flat to the floor throughout — if the lats or external rotators are restricted some elevation off the surface is expected; allow comfortable contact only.
- Arching the lower back as the arms approach overhead — gently manage rib position without forcefully flattening the lumbar spine into the floor.
- Rushing through the arc using momentum — the benefit comes from the controlled, slow sweep; fast repetitions bypass the mobility work.
Modifications and progressions
- Begin with elbows bent at 90° (goalpost position) if straight-arm slides create shoulder discomfort, then gradually extend the arms as range allows.
- Slide one arm at a time to allow closer attention to each shoulder independently and reduce the bilateral coordination demand.
