How to perform Chair Upper Body Stretch
- Sit on the edge of a chair, gripping the back of it.
- Straighten your arms, keeping your back straight, and pull your upper body forward so you feel a stretch. Hold for 20-30 seconds.
Muscles worked
- Shoulders (primary): raises and rotates the arms and drives everything overhead.
- Biceps (secondary): bends the elbow and turns the palm up during pulls and curls.
- Chest (secondary): pushes the arms forward and across the body — your horizontal pressing power.
Sets & reps by goal
| Goal | Sets × reps | Load | Rest |
|---|---|---|---|
| Strength | 3–5 × 3–5 | Heavy (~85%+) | 2–3 min |
| Hypertrophy | 3–4 × 8–12 | Moderate (~65–75%) | 60–90 s |
| Endurance | 2–3 × 15–20 | Lighter (~50–60%) | 30–45 s |
As a mobility drill, hold each position for 20–40 seconds (or move slowly for reps) rather than training it to a heavy load.
Form tips
- Keep the ribs down and the glutes tight so the lower back doesn't arch to 'help' the weight up.
- Set the seat and pads so the machine's pivot lines up with the joint you're training before your first rep.
- Ease in until you feel mild tension, never pain, and breathe out as you sink a little deeper.
- Control the lowering phase — a 2–3 second descent builds more than dropping the weight.
Common mistakes
- Pressing with the lower back arched instead of a braced, stacked torso.
- Leaving the seat or range on a setting that forces the joint into an awkward angle.
- Bouncing into the stretch instead of holding it steadily.
