Exercise guide

Lever One Arm Shoulder Press Plate Loaded

  • Intermediate
  • Compound
  • Rep-based
  • Back
  • Shoulders

This unilateral compound movement isolates the deltoids while allowing for a greater range of motion and core stability than bilateral presses. It is highly effective for correcting muscular imbalances and improving overhead pressing strength through a fixed, safe path.

Equipment

  • Leverage machine

Setup

  1. Load the desired weight onto the machine and adjust the seat height so the handles are at shoulder level.
  2. Sit firmly with your back against the pad and feet flat on the floor to create a stable base.
  3. Grasp the handle with one hand using a neutral or overhand grip, keeping your wrist stacked directly over your elbow.
  4. Place your non-working hand on your hip or the machine's side handle to maintain torso alignment.

How to do it

  1. Exhale as you press the handle upward in a controlled arc until your arm is fully extended but the elbow is not locked out.
  2. Inhale as you slowly lower the weight back to the starting position, stopping just before the weight plates touch.
  3. Maintain a controlled 2-0-2-0 tempo, ensuring the shoulder remains under constant tension.
  4. Complete the full set on your weaker side first to ensure equal effort across both shoulders.

Form checklist

  • Keep your core braced and lower back pressed against the seat to prevent excessive arching.
  • Ensure your elbow stays slightly in front of your shoulder in the scapular plane rather than flaring out to the side.
  • Keep your shoulders depressed; do not allow your trap to shrug toward your ear as you press.
  • Maintain a neutral neck position with your gaze fixed straight ahead.

Pro tips

  • Focus on driving the elbow 'up and in' toward your midline to maximize the contraction of the anterior and medial deltoid.
  • Use your non-working arm to actively grip the seat or side handle, which helps create 'irradiation' and increases total body stability for a heavier press.

Make it harder

  • Implement a 3-second eccentric (lowering) phase to increase mechanical tension and muscle fiber damage.
  • Add a 1-second pause at the bottom of the movement to eliminate all momentum before the next rep.
