Setup
- Lie face down on a flat mat with your legs extended straight and the tops of your feet resting on the floor.
- Extend your arms directly out to your sides at a 90-degree angle from your torso, forming a 'T' shape.
- Rotate your wrists so your thumbs are pointing toward the ceiling.
- Tuck your chin slightly and rest your forehead on the floor to maintain a neutral cervical spine.
How to do it
- Exhale as you squeeze your shoulder blades together to lift your arms off the floor as high as comfortable.
- Hold the peak contraction for 1-2 seconds, focusing on the tension in the middle of your back.
- Inhale as you slowly lower your arms back toward the floor with a controlled 2-second tempo.
- Avoid letting your arms fully rest on the floor between repetitions to maintain constant tension.
Form checklist
- Keep your thumbs pointed toward the ceiling to maximize external rotation.
- Ensure your shoulders stay down and away from your ears to avoid overactive upper traps.
- Keep your forehead down to prevent neck strain.
- Initiate the lift by retracting the shoulder blades rather than just moving the arms.
Pro tips
- Focus on the 'mind-muscle connection' by imagining you are trying to pinch a pencil between your shoulder blades at the top of the movement.
- Keep your glutes and core lightly engaged to stabilize your lower back and prevent excessive arching.
Make it harder
- Hold light weights, such as small dumbbells or water bottles, to increase the resistance.
- Perform the movement with a 5-second isometric hold at the top of every repetition.
