Exercise guide

Lever Decline Single Arm Chest Press

  • Intermediate
  • Compound
  • Rep-based
  • Chest
  • Shoulders
  • Upper arms
  • Waist

This unilateral compound movement targets the lower pectoral fibers and anterior deltoids while allowing for a greater range of motion and improved muscular balance. The decline angle shifts the focus to the sternocostal head of the chest, often reducing shoulder strain compared to flat or incline presses.

Muscles worked

Primary

  • Pectorals

Secondary

  • Abs
  • Serratus anterior

Equipment

  • Leverage machine

Setup

  1. Position a decline bench (set to approximately 15-30 degrees) in front of the leverage machine so the handles align with your lower chest.
  2. Lie back on the bench, securing your feet firmly in the foot pads to prevent sliding.
  3. Grasp the handle with one hand using an overhand grip, ensuring your wrist is stacked directly over your elbow.
  4. Place your non-working hand on your hip or the side of the bench to help stabilize your torso.

How to do it

  1. Inhale as you lower the handle toward the side of your chest in a controlled manner, keeping your elbow at a 45-degree angle from your torso.
  2. Exhale forcefully as you press the handle back to the starting position, focusing on driving through the base of your palm.
  3. Maintain a steady tempo of 2 seconds on the way down and 1 second on the way up, stopping just short of a full elbow lockout.
  4. Complete the full set of repetitions on one side before switching to the other arm.

Form checklist

  • Keep your shoulder blades retracted and pinned firmly against the bench throughout the set.
  • Ensure your lower back remains in contact with the bench; do not arch your spine to compensate for the weight.
  • Keep your elbow directly under the wrist to maintain a vertical line of force and protect the joint.
  • Avoid rotating your torso toward the working arm; keep your chest square to the ceiling at all times.

Pro tips

  • Focus on 'squeezing' your bicep against the side of your chest at the top of the movement to maximize the contraction of the lower pectoral fibers.
  • Use your free hand to touch the working pectoral muscle to enhance the mind-muscle connection and ensure proper activation.

Make it harder

  • Incorporate a 2-second pause at the bottom of the movement to eliminate momentum and increase intensity.
  • Implement a slow 4-second eccentric (lowering) phase to maximize time under tension and muscle fiber recruitment.
