Muscles worked

Primary

  • Pectorals

Secondary

  • Abs
  • Serratus anterior

Equipment

  • Leverage machine

Setup

  1. Adjust the seat height so the handles are aligned with your upper chest or collarbone level.
  2. Sit firmly against the backrest with your feet planted flat on the floor for stability.
  3. Grip one handle with an overhand or neutral grip, ensuring your wrist is stacked directly over your elbow.
  4. Place your non-working hand on your thigh or the machine's side handle to stabilize your torso.

How to do it

  1. Exhale as you press the lever forward and slightly upward until your arm is fully extended without locking the elbow.
  2. Inhale as you slowly lower the weight back toward the starting position, feeling a deep stretch in the upper chest.
  3. Maintain a controlled tempo, taking approximately two seconds to lower the weight and one second to press it.
  4. 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.
