Setup
- Sit tall on the edge of a flat bench with your feet planted firmly on the ground.
- Interlace your fingers behind your head with elbows pointing out to the sides.
- Engage your core to maintain a neutral spine and keep your gaze fixed straight ahead.
How to do it
- Inhale deeply as you pull your elbows back as far as possible, actively squeezing your shoulder blades together.
- Exhale and hold the peak contraction for 3-5 seconds, focusing on the stretch across the pectoral muscles.
- Slowly release the tension and return your elbows to the starting position in a controlled manner.
- Perform each repetition with a slow tempo, emphasizing the pause at the end of the range of motion.
Form checklist
- Keep your shoulders depressed and away from your ears to avoid shrugging.
- Do not allow your head to poke forward or your chin to drop as you pull back.
- Keep your ribcage tucked; avoid arching your lower back to gain extra range.
- Ensure the movement is driven by the shoulder blades (scapulae) rather than just the arms.
Pro tips
- Imagine you are trying to crush a grape between your shoulder blades to maximize trapezius engagement.
- Focus on the 'opening' sensation in the chest rather than just the backward movement of the elbows.
Make it harder
- Extend your arms straight out to the sides in a 'T' position to increase the lever arm and stretch intensity.
- Hold the peak contraction for 10-15 seconds to turn the stretch into an isometric strengthening exercise for the mid-back.
