Back Bend Over Bench Stretch
- Intermediate
- Compound
- Timed hold
- Back
- Lower legs

This compound movement utilizes a dumbbell to provide a deep thoracic stretch while challenging the core and upper body through a large range of motion. It is highly effective for expanding the ribcage, improving shoulder mobility, and strengthening the serratus anterior and abdominals.

Setup
- Lie perpendicular across a flat bench so only your upper back and shoulders are supported.
- Place your feet flat on the floor, hip-width apart, with your knees bent at a 90-degree angle.
- Hold a single dumbbell with both hands using a diamond grip (palms against the underside of the top plate) directly over your chest.
- Drop your hips slightly below the level of the bench to create a slight arch and engage your core.
How to do it
- Inhale deeply and slowly lower the dumbbell in a controlled arc behind your head while keeping a slight, fixed bend in your elbows.
- Lower the weight until you feel a significant stretch in your chest, lats, and abdominals.
- Exhale and pull the dumbbell back to the starting position over your chest using your pectorals and serratus.
- Maintain a slow 3-second tempo on the way down and a controlled 1-2 second tempo on the way up.
Form checklist
- Keep your hips lower than the bench to maximize the stretch on the anterior chain.
- Maintain a consistent, slight bend in the elbows; do not turn this into a tricep extension.
- Ensure your neck remains in a neutral position to avoid unnecessary strain.
- Keep your core braced throughout the movement to stabilize your spine.
Pro tips
- Focus on 'opening' your ribcage as the weight descends to maximize the engagement of the intercostals and serratus.
- At the top of the movement, squeeze your chest together to emphasize pectoral activation.
Make it harder
- Lower your hips further toward the floor to increase the leverage and stretch on the abdominal wall.
- Add a 3-second isometric pause at the bottom of the stretch to increase time under tension.
