Setup
- Adjust the seat height so the handles are aligned with your upper chest or collarbone level.
- Sit firmly against the backrest with your feet planted flat on the floor for stability.
- Grip one handle with an overhand or neutral grip, ensuring your wrist is stacked directly over your elbow.
- Place your non-working hand on your thigh or the machine's side handle to stabilize your torso.
How to do it
- Exhale as you press the lever forward and slightly upward until your arm is fully extended without locking the elbow.
- Inhale as you slowly lower the weight back toward the starting position, feeling a deep stretch in the upper chest.
- Maintain a controlled tempo, taking approximately two seconds to lower the weight and one second to press it.
- Complete all repetitions on one side before switching to the other arm.
Form checklist
- Keep your shoulder blades retracted and pinned firmly against the backrest.
- Ensure your elbow stays tucked at a 45 to 60-degree angle rather than flaring out to the side.
- Keep your hips and glutes glued to the seat; do not twist your torso to help move the weight.
- Maintain a neutral wrist position, preventing it from bending backward under the load.
Pro tips
- Focus on driving your bicep toward the center of your chest at the top of the movement to maximize pectoral shortening.
- Pause for one second at the bottom of the movement to eliminate momentum and force the chest to do the work from a dead stop.
Make it harder
- Implement a 3-second eccentric (lowering) phase to increase time under tension.
- Add a brief isometric hold at the point of peak contraction to enhance mind-muscle connection.
