Smith Standing Behind Head Military Press

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

This variation shifts the focus toward the lateral and posterior deltoids by altering the shoulder's plane of motion compared to a front press. The Smith machine's fixed path provides the stability needed to safely perform this behind-the-neck movement while heavily engaging the traps and triceps.

Muscles worked

  • Rotator cuff
  • Serratus anterior

Equipment

  • Smith machine

Setup

  1. Set the Smith machine bar to approximately upper-chest height.
  2. Stand inside the machine with feet shoulder-width apart and a slight bend in the knees for stability.
  3. Grasp the bar with a wide overhand grip, ensuring your forearms are vertical when the bar is at its lowest point.
  4. Position yourself slightly forward so the bar is aligned with the base of your neck/upper traps.

How to do it

  1. Rotate the bar to unlock it and take the weight across your upper traps.
  2. Exhale as you press the bar vertically in a smooth motion until your arms are fully extended but not locked out.
  3. Inhale as you slowly lower the bar back down to the base of your neck, maintaining full control.
  4. Maintain a tempo of 2 seconds down and 1 second up to maximize muscle fiber recruitment.

Form checklist

  • Keep your core braced and glutes squeezed to prevent excessive arching of the lower back.
  • Ensure your elbows stay directly under the bar throughout the entire range of motion.
  • Keep your head in a neutral position; do not crane your neck forward to avoid the bar.
  • Stop the descent if you feel any sharp discomfort in the shoulder capsule.

Pro tips

  • Focus on 'pulling' the bar apart with your hands during the press to increase lateral deltoid activation.
  • Stop the bar an inch above your traps to keep constant tension on the shoulders and protect the cervical spine.

Make it harder

  • Incorporate a 2-second isometric pause at the bottom of each rep to eliminate momentum.
  • Use a 4-second eccentric (lowering) phase to increase time under tension and metabolic stress.
