How to do it

Setup

  1. Lie flat on your back on the floor or an exercise mat, with knees bent and feet flat on the ground.
  2. Hold an EZ-bar above your upper chest or forehead with an overhand grip on the inner bends, arms extended.

Movement

  1. Lower the bar under control by bending at the elbows until the weight plates gently touch the floor overhead behind your head.
  2. Allow the weight to come to a brief, dead-stop pause on the floor without letting tension leave the triceps completely.
  3. Drive the weight back up by extending your elbows until your arms return to the starting position.

Breathing

Inhale as you lower the bar to the floor, and exhale as you press back up to full extension.

Cues

  • Keep upper arms stationary
  • Dead stop on the floor, no bouncing
  • Drive through the triceps

Common faults

Bouncing the plates off the floor to gain momentum.
Pause completely on the floor to eliminate the stretch reflex before extending.
Flaring the elbows outward excessively during the press.
Keep the elbows tucked shoulder-width apart and pointing toward the ceiling throughout the repetition.

Safety

  • Ensure standard-sized plates or bumpers are used if needed so the bar settles at an appropriate height overhead without risking facial contact.
