How to Perform

Lie flat on a bench with feet on the floor. Grip the EZ-bar overhand slightly narrower than shoulder-width and extend arms above your chest.

  1. Bend elbows to lower the bar slowly toward your forehead.
  2. Keep upper arms stationary and elbows tucked.
  3. Pause briefly at the bottom for a stretch.
  4. Extend elbows to press the bar back up.
  5. Squeeze triceps at full extension without locking elbows.
  6. Repeat for reps while maintaining control.

Coaching Tips

Form Cues

  • Elbows tucked tight
  • Upper arms perpendicular
  • Control the descent
  • Squeeze at top
  • Avoid flaring elbows

Breathing

Inhale as you lower the bar; exhale as you extend it. Brace core throughout.

Tempo

3-1-2

Range of Motion

Lower until forearms are parallel to the floor or bar nears forehead; extend to straight arms without hyperextending elbows.

Safety

Safety Notes

  • Start with light weight to master form
  • Use spotter for heavy loads
  • Adjust if elbow pain occurs
  • Keep core engaged to protect back

Spotting

Spotter assists unracking and can support bar during heavy sets; stand at head end to lift off chest if needed.

Common Mistakes

  • Flaring elbows outward
  • Dropping bar too fast
  • Hyperextending elbows
  • Arching lower back

When to Avoid

  • Acute elbow pain
  • Shoulder impingement

Flexibility Needed

  • Full elbow extension
  • Shoulder flexion above 90 degrees

Build Up First

  • Basic overhead pressing form
  • Wrist neutral grip comfort
