Lever Incline Single Arm Chest Press

  • Compound
  • Rep-based
  • Chest
  • Shoulders

This unilateral movement targets the clavicular head of the pectoralis major while improving muscular symmetry and core stability. By pressing one arm at a time, you can achieve a deeper contraction and better focus on the mind-muscle connection in the upper chest.

Muscles worked

Primary

  • Pectorals

Secondary

  • Abs
  • Serratus anterior

Equipment

  • Leverage machine

Setup

  1. Position the incline bench at a 30 to 45-degree angle within the leverage machine.
  2. Sit firmly with your back against the pad and feet planted wide for a stable base.
  3. Grasp the handle with an overhand grip, aligning the handle with your upper chest level.
  4. Place your non-working hand on your thigh or the side of the bench to prevent torso rotation.

How to do it

  1. Exhale and press the lever upward until your arm is nearly straight, focusing on driving your inner elbow toward your midline.
  2. Hold the peak contraction for one second, squeezing the upper pectoral muscle.
  3. Inhale as you slowly lower the weight back down over a 3-second count until you feel a comfortable stretch.
  4. Complete all repetitions on one side before switching to the other to maintain constant tension.

Form checklist

  • Keep your shoulder blades pinned back and down against the pad throughout the set.
  • Ensure your elbow tracks at a 45-degree angle relative to your torso rather than flaring out.
  • Maintain a neutral wrist position to ensure the force is transferred directly through the forearm.
  • Keep your hips and glutes glued to the seat to avoid using momentum or arching the lower back.

Pro tips

  • Imagine trying to touch your bicep to your upper chest at the top of the movement for maximum fiber recruitment.
  • Use your non-working hand to touch the working pectoral muscle to enhance the mind-muscle connection.

Make it harder

  • Implement a '1.5 rep' style where you perform a full rep followed by a half rep from the bottom to the midpoint.
  • Add a slow 5-second eccentric (lowering) phase to increase time under tension.
