Setup
- Adjust the seat height so the machine handles align with your mid-to-lower chest level.
- Sit firmly with your back pressed against the pad and your feet planted wide on the floor for stability.
- Grasp one handle with a firm grip, ensuring your elbow is positioned slightly below your shoulder.
- Place your non-working hand on your thigh or the side of the seat to maintain a square torso.
How to do it
- Exhale as you press the handle forward in a controlled arc until your arm is nearly straight.
- Squeeze your chest at the peak of the movement for one second, avoiding a forceful lockout of the elbow.
- Inhale as you slowly lower the weight back toward your chest, maintaining constant tension on the muscle.
- Perform the movement with a 2-0-2-1 tempo (2 seconds out, 0 pause, 2 seconds back, 1 second squeeze).
Form checklist
- Keep your shoulder blades retracted and pinned against the backrest throughout the set.
- Avoid rotating your torso or lifting your hip off the seat to help move the weight.
- Ensure your wrist remains neutral and does not bend backward under the load.
- Keep your feet flat on the ground to prevent swaying or loss of balance.
Pro tips
- Focus on driving your bicep toward your sternum at the top of the rep to maximize pectoral shortening.
- Use your non-working hand to touch the working pectoral muscle to enhance the mind-muscle connection.
Make it harder
- Implement a 3-second eccentric (lowering) phase to increase time under tension.
- Add a brief pause at the bottom of the rep just before the weight stack touches to keep the muscle loaded.
