The Back Pec Stretch on an incline bench is a restorative movement that opens the chest and shoulders while lengthening the lats. It is highly effective for improving thoracic mobility and reversing the 'hunched' posture caused by sitting or heavy pressing.

Setup
- Stand facing the back of an incline bench set to approximately a 45-degree angle.
- Place your palms or forearms on the top edge of the backrest with a shoulder-width grip.
- Step back until your feet are hip-width apart and your arms are fully extended, creating a 'V' shape with your body.
How to do it
- Inhale to prepare, then exhale as you hinge at the hips and sink your chest toward the floor.
- Keep your arms straight and push your hips back to create a long line from your hands to your tailbone.
- Hold the stretch for 20-30 seconds, breathing deeply into the sides of your ribcage to expand the lats.
- Slowly lift your chest and step forward toward the bench to safely release the tension.
Form checklist
- Keep your neck neutral by tucking your chin slightly; your ears should stay aligned with your biceps.
- Maintain a slight bend in the knees to prevent hamstring tension from limiting the shoulder stretch.
- Avoid 'dumping' into the lower back by keeping your ribs tucked and your core slightly braced.
- Ensure your weight is distributed evenly through your heels and mid-foot.
Pro tips
- Rotate your palms to face each other or slightly upward to increase the stretch in the lats and external rotators of the shoulder.
- Focus on 'melting' your heart toward the floor to maximize thoracic extension rather than just pushing your shoulders down.
- Contract your glutes slightly to stabilize the pelvis and isolate the stretch to the upper body.
Make it harder
- Perform the stretch unilaterally by placing only one hand on the bench and rotating your torso slightly away from the stretching arm.
- Place your elbows on the bench and bring your hands together behind your head (prayer position) to increase the stretch on the triceps and lats.
