It is highly effective for counteracting 'rounded shoulders' by strengthening the muscles responsible for pulling the shoulder blades down and back.

Setup
- Lie face down on a flat, comfortable surface with your legs extended straight behind you.
- Extend your arms directly overhead, parallel to each other, so your body forms a straight 'I' shape.
- Rest your forehead on the floor to maintain a neutral cervical spine and tuck your chin slightly.
- Position your hands so your thumbs are pointing toward the ceiling.
How to do it
- Exhale and lift your straight arms toward the ceiling as high as comfortable without lifting your chest off the floor.
- Squeeze your shoulder blades together and down toward your back pockets at the top of the movement.
- Pause for one second at the peak of the contraction to maximize muscle fiber recruitment.
- Inhale as you slowly lower your arms back to the starting position under full control.
Form checklist
- Keep your elbows fully locked throughout the entire range of motion.
- Ensure your forehead stays in contact with the floor to prevent neck compensation.
- Keep your core engaged and glutes squeezed to prevent your lower back from arching.
- Focus on moving the arms from the shoulder joint rather than just lifting the hands.
Pro tips
- Think about 'lengthening' your arms toward the wall in front of you as you lift to create space in the shoulder joint.
- Initiate the lift by depressing your shoulder blades away from your ears to ensure the lower traps are doing the work.
Make it harder
- Hold the top position for 3-5 seconds on every repetition to increase time under tension.
- Hold a small weight, such as a light dumbbell or even a water bottle, in each hand while maintaining perfect form.
