PNF Shoulder Stretch

A tight posterior shoulder limits reaching across the body and can pinch during pressing. Pulling the arm across your chest sets the stretch; a brief isometric push against your holding arm then lets you draw it further. Useful for lifters and overhead athletes who feel blocked reaching behind or across.

How to do it

  1. 1

    Stand or sit tall and bring one straight arm across the front of your body at chest height.

  2. 2

    Use the opposite hand to draw the arm across until you feel a firm stretch in the back of the shoulder.

  3. 3

    Contract: press the stretching arm back against your holding hand as if pulling it away from the body, holding the isometric at about 25 percent for six to ten seconds.

  4. 4

    Relax the shoulder fully for two to three seconds and exhale.

  5. 5

    Draw the arm further across into the new range and hold briefly.

  6. 6

    Repeat the cycle three to four times, then switch arms.

Tips

  • Keep the shoulder pulled down away from the ear so you stretch the delt, not the neck.
  • Draw the arm across at chest height, not up under the chin, to target the posterior shoulder.
  • Keep the torso square; avoid twisting to fake extra range.

Variations

Common mistakes

  • The holding hand gives ground during the six-to-ten-second push, so the arm drifts away from the chest and the isometric becomes a slow shove.
  • Effort during the contract phase climbs toward maximum, and a shoulder working that hard guards rather than releases; a quarter of your strength is the target.
  • The elbow softens a little more with each cycle, shortening the lever until the pull sits in the upper arm instead of behind the shoulder.
  • Cycles keep stacking past four because every one feels slightly better, which leaves the back of the shoulder sore the next day rather than looser.
  • You draw the arm deeper while still braced from the push; let the shoulder go completely soft for two to three seconds first, or you are pulling on a muscle that is still working.

Frequently asked

How many rounds of the PNF shoulder stretch should I do per arm?
Three or four cycles per arm, done after upper-body training or on a mobility day, two or three times a week. Each cycle is a six-to-ten-second push at about a quarter effort, a full relax, then a short hold in the new range. The session is over when a cycle no longer buys extra range; that is the day's limit, and further passes only make the shoulder sore.
How do I make the PNF shoulder stretch easier or harder?
For an easier version, drop the contract phase and simply hold the arm across the chest, or shorten the push to five seconds at very light effort. For more, do it lying on your back so the floor keeps the shoulder blade flat, or have a partner hold the arm while you press against them, which gives steadier resistance than your own hand.
Who is the PNF shoulder stretch for?
It suits overhead athletes and lifters who feel blocked reaching across the body and whose plain holds have stopped producing range. The contract-relax cycle asks you to judge effort, which is why it sits above a basic stretch in difficulty. It is a poor choice on a shoulder that pinches inside the joint during the pull, and a poor warm-up right before max overhead work, where you want the joint feeling tight rather than freshly opened.
