The one arm shoulder flexor stretch is a standing bodyweight stretch that targets the front of the shoulder by extending one arm behind the body, elongating the shoulder flexor region (anterior shoulder area). It requires no equipment and is commonly used as a warm-up or cool-down around pressing movements to maintain shoulder mobility and reduce front-shoulder tightness.
Cómo hacer el One Arm Shoulder Flexor Stretch
- 1Stand tall with your feet hip-width apart and your core lightly braced.
- 2Extend one arm straight behind your body at roughly hip height, palm facing inward or slightly upward.
- 3Reach your arm as far back as comfortable, allowing your shoulder to move into extension without rotating your torso.
- 4Hold the end-range position and feel the stretch along the front of the shoulder.
- 5Keep your chest lifted and your shoulder blade gently pulled down and back to deepen the stretch.
- 6Breathe steadily and hold for 20–30 seconds without forcing the arm further back.
- 7Release slowly, return your arm to your side, and repeat on the opposite arm.
Consejos de técnica
- Avoid rotating your torso to reach further back — keep your hips and chest square to the front so the stretch stays in the shoulder, not the spine.
- Lead with a gentle exhale as you settle into the end range; muscles relax more readily when you breathe out.
- Keep a slight bend in the elbow if a fully straight arm causes discomfort at the elbow joint.
- Use a wall or door frame behind you for a passive-assist version: place the back of your hand against the surface and lean away to increase the stretch.
Errores comunes
- Rotating the torso to get the arm further back — this cheats the stretch away from the shoulder flexors and into the spine.
- Forcing the arm aggressively into hyperextension, which can strain the shoulder joint capsule rather than lengthening the target muscles.
- Holding your breath, which increases muscular tension and reduces the effectiveness of the stretch.
- Shrugging the shoulder upward during the stretch, which shortens the range of motion and creates neck tension instead of shoulder release.
Preguntas frecuentes
What does the one arm shoulder flexor stretch target?
It stretches the front of the shoulder — the shoulder flexor region, including the anterior deltoid area — by moving the arm into extension behind the body, which is the opposite of shoulder flexion.
When should I do this stretch?
It works well both as a warm-up before pressing or overhead exercises and as a cool-down afterward. Holding for 20–30 seconds per side post-workout is a common approach to reduce front-shoulder tightness.
How long should I hold the stretch?
Aim for 20–30 seconds per side for a general mobility stretch. For a warm-up, shorter dynamic pulses of 5–10 seconds are often more appropriate than a prolonged static hold.
Can I use a wall to make this stretch more effective?
Yes. Place the back of your hand or wrist against a wall at hip height, then gently lean your body forward and away from the wall. This passive assist lets you control the intensity without muscular effort.
Is this stretch safe for people with shoulder injuries?
Gentle shoulder mobility work can support recovery, but anyone with a current shoulder injury or pain should consult a physiotherapist before performing this stretch. Stop immediately if you feel sharp or pinching pain.
