Setup
- Sit on the edge of a flat bench with your feet flat on the floor and knees bent at 90 degrees.
- Place your palms flat on the bench behind your hips with fingers pointing away from your body.
- Straighten your arms and roll your shoulders back to set your starting position.
How to do it
- Inhale deeply and lift your sternum toward the ceiling, retracting your shoulder blades.
- Exhale as you slowly slide your hips forward and away from your hands until you feel a deep stretch in the chest and front of the shoulders.
- Hold the position for 30 seconds, focusing on deep, diaphragmatic breathing.
- Slowly slide your hips back toward your hands to safely exit the stretch.
Form checklist
- Keep your shoulders depressed and pulled away from your ears.
- Maintain a proud chest and avoid rounding the upper back.
- Ensure your palms stay firmly planted on the bench throughout the movement.
- Keep your neck in a neutral position, avoiding excessive backward tilting.
Pro tips
- Rotate your inner elbows (antecubital fossa) forward to increase the stretch through the biceps and forearm flexors.
- Actively squeeze your shoulder blades together and down to maximize the 'depressor' and 'retractor' components of the stretch.
Make it harder
- Walk your feet further out to allow the hips to move further forward, increasing the angle of shoulder extension.
- Perform the stretch with fingers pointing toward your glutes to significantly intensify the forearm and wrist stretch.
