Setup

  1. Stand upright with your feet shoulder-width apart and your core engaged.
  2. Place the arm you want to stretch behind your back, with the back of your hand resting against your lower spine.
  3. Hold a stick or PVC pipe vertically behind your back with the lower hand.
  4. Reach your opposite arm over your shoulder to grab the top of the stick.

How to do it

  1. Gently pull the top of the stick forward and down with your upper hand to increase the internal rotation of the lower arm.
  2. Inhale deeply as you find the initial stretch, and exhale as you slowly increase the range of motion.
  3. Hold the stretch for 30-60 seconds while maintaining a steady, controlled breathing pattern.
  4. Slowly release the tension and repeat the process on the opposite side.

Form checklist

  • Keep your chest tall and avoid rounding your shoulders forward.
  • Ensure your neck remains neutral and your head does not jut forward.
  • Keep the shoulder of the arm being stretched pulled down and away from your ear.
  • Stop immediately if you feel sharp or pinching pain in the shoulder joint.

Pro tips

  • Use a contract-relax technique: gently push your lower hand back against the stick for 5 seconds, then relax and pull deeper into the stretch.
  • Focus your mind on the front of the shoulder blade, visualizing the muscle lengthening as you exhale.

Make it harder

  • Gradually slide your lower hand further up your spine toward your shoulder blades before applying tension with the stick.
  • Perform the stretch while standing with your back against a wall to ensure your spine and head remain perfectly neutral.
