The back pec stretch is a bodyweight mobility move that lengthens the lats (latissimus dorsi), the chest (pectoralis major, both the clavicular and sternal heads), and the teres major. Using only your body weight against a fixed support, it opens up the shoulders and upper back, making it a useful warm-up or cool-down for pressing and pulling work.

How to do the Back Pec Stretch

  1. 1Stand facing a sturdy upright support such as a squat-rack post, doorframe, or pole, with your feet about hip-width apart.
  2. 2Reach up and grip the support overhead with one or both hands, arms extended above and slightly in front of you.
  3. 3Step your feet back and hinge slightly at the hips so your arms straighten and your torso lowers between them.
  4. 4Ease your chest down and back, letting your shoulders and upper back open until you feel a mild stretch through your lats, chest, and the teres major along the back of your armpit.
  5. 5Keep a long spine and relaxed neck, breathing slowly as you settle into the position.
  6. 6Hold the stretch for 20–30 seconds at a comfortable depth, never forcing past mild tension.
  7. 7Slowly walk your feet back in and stand tall to release, then repeat for 2–3 rounds.

Form tips

  • Ease into the stretch slowly and stop at the point of mild tension, not pain — stretching should never feel sharp.
  • Breathe steadily and exhale as you sink deeper; holding your breath tightens the muscles you are trying to lengthen.
  • Avoid bouncing or jerking into the end range — hold the position still so the lats and chest can relax and release.
  • Adjust your hand height and how far you step back to dial the stretch in or out, keeping it comfortable throughout.

Common mistakes

  • Pushing into pain instead of mild tension, which triggers the muscle to tighten protectively and risks straining the shoulder.
  • Bouncing or pulsing at the end range, which can overstretch the tissue and cause small tears rather than a smooth release.
  • Holding your breath, which keeps the lats, chest, and teres major tense and limits how much they relax.
  • Rounding or overarching the spine instead of staying long, which shifts the load off the target muscles and onto the lower back.

Frequently asked questions

What muscles does the back pec stretch work?

It stretches the lats (latissimus dorsi), the chest (pectoralis major, both clavicular and sternal heads), and the teres major along the back of the shoulder.

How long should I hold the back pec stretch?

Hold each rep for about 20–30 seconds at a comfortable depth, and repeat for 2–3 rounds. Aim for mild tension you can breathe through, not pain.

Is the back pec stretch good for beginners?

Yes. It uses only your body weight against a fixed support and lets you control the depth, so you can ease in slowly and stop at mild tension — making it beginner-friendly.

When should I do the back pec stretch?

Use it as part of a warm-up to open the shoulders before pressing or pulling, or as a cool-down afterward to lengthen the lats and chest. Stretch only to mild tension and never bounce.
