Dynamic Chest Stretch
This movement sweeps your arms open and closed in a controlled, rhythmic arc to loosen the chest and upper back before activity. Years of sitting — at desks, in cars, on couches — tend to pull the shoulders forward and tighten the chest. A few reps of this stretch counteracts that rounding and helps your shoulders move freely for whatever comes next. No equipment needed, and you can do it standing anywhere.

Form cues
- 01
Stand with your feet about shoulder-width apart and a soft bend in your knees — not locked straight.
- 02
Bring both arms straight out in front of you at chest height, palms facing each other, fingertips touching.
- 03
Keep your arms at shoulder height the entire time — resist the urge to let them drift up or down.
- 04
Swing both arms out to your sides in a wide arc, like you're opening a big set of double doors.
- 05
Let your shoulder blades squeeze together at the back as your arms reach their widest point — that squeeze is the goal.
- 06
Swing the arms back to center in a smooth, controlled motion — not a flop.
- 07
Start slowly for the first two or three reps, then gradually increase your speed as your chest loosens up.
- 08
Keep your chin level and your chest lifted — don't let your head jut forward as the arms swing back.

Common mistakes
Arms dropping below shoulder height — if your hands end up near your hips at the back, you're losing the chest stretch; keep them level with your shoulders throughout.
Swinging too fast too soon — if you feel a sharp pull or your arms are flailing, slow down and build speed gradually over several reps.
Holding your breath — if you notice tension in your neck or face, exhale as the arms open wide and inhale as they come back together.
Leaning the torso backward as the arms swing open — your spine should stay upright; if your lower back arches, tighten your stomach slightly to stay tall.
Bending the elbows mid-swing — bent arms shorten the lever and reduce the stretch; keep them long but not rigidly locked.
Scale it
Easier and harder variations
Easier
Stand next to a wall or hold the back of a sturdy chair with one hand, then do single-arm chest sweeps until you feel steady enough to go hands-free.
Use this if balance feels uncertain or you're just getting started.
Harder
Hold a light resistance band looped around both hands at chest width — the band adds gentle tension as you open your arms, deepening the chest stretch.
Use this once the bodyweight version feels easy and you want more range-of-motion work.
Note
If one shoulder is sore or recently treated, do the movement with just the unaffected arm, or reduce the range so you only open as wide as is comfortable — even a small arc is beneficial.
Use this with a shoulder injury, recent rotator cuff work, or post-surgical clearance.
