Setup
- Stand with your feet shoulder-width apart and maintain an upright posture with a neutral spine.
- Place your palms together in front of your chest at sternum height, similar to a prayer position.
- Position your elbows so they are flared out to the sides, roughly parallel to the floor.
How to do it
- Exhale as you press your palms together as hard as possible, focusing on driving the force from your chest muscles.
- Maintain this maximum isometric tension for 5–10 seconds while taking short, shallow breaths.
- Inhale as you slowly reduce the pressure, but maintain a slight engagement in the chest between repetitions.
- Repeat for the desired number of sets, focusing on a slow and controlled application of force.
Form checklist
- Keep your shoulders pulled down and back to prevent your traps from taking over.
- Ensure your forearms remain parallel to the ground to keep the tension on the pectorals.
- Engage your core to stabilize your torso and prevent your lower back from arching.
- Focus the pressure through the heels of your palms rather than just your fingers.
Pro tips
- Imagine you are trying to crush a small, hard object between your palms to maximize pectoral fiber recruitment.
- Vary the height of your hands—from chin level down to the lower chest—to target the upper, middle, and lower fibers of the chest.
Make it harder
- Hold an EZ barbell vertically between your palms and squeeze the ends of the bar together to add external weight and stability challenge.
- Perform 'pulses' by rapidly oscillating between 80% and 100% maximum squeeze pressure for the duration of the set.
