How to perform Dynamic Chest Stretch
- Stand with your hands together, arms extended directly in front of you. This will be your starting position.
- Keeping your arms straight, quickly move your arms back as far as possible and back in again, similar to an exaggerated clapping motion. Repeat 5-10 times, increasing speed as you do so.
Muscles worked
- Chest (primary): pushes the arms forward and across the body — your horizontal pressing power.
- Back (secondary): pulls the arms down and toward the torso and keeps the spine stable.
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
- Set the shoulder blades down and back and keep them pinned there so the chest, not the front of the shoulders, does the pressing.
- Own the largest range you can control with clean form before you chase extra reps.
- Ease in until you feel mild tension, never pain, and breathe out as you sink a little deeper.
- Warm up the pattern with a couple of lighter, submaximal sets before your working sets.
Common mistakes
- Flaring the elbows straight out to the sides, which puts the shoulder joint in a weak, vulnerable spot.
- Cutting the range short to squeeze out extra reps instead of owning each full one.
- Bouncing into the stretch instead of holding it steadily.
