How to Perform

Sit on the preacher bench with upper arms and chest against the slanted pad. Grip the EZ barbell underhand at shoulder width and extend arms nearly fully with elbows on the pad.

  1. Exhale and curl the barbell upward by contracting your biceps, keeping upper arms stationary.
  2. Squeeze biceps at the top when bar reaches shoulder level.
  3. Inhale and slowly lower the barbell to starting position with control.
  4. Maintain slight elbow bend at bottom to keep tension on biceps.
  5. Repeat for prescribed reps without swinging.

Coaching Tips

Form Cues

  • Keep elbows glued to pad
  • Squeeze biceps hard
  • Control the eccentric
  • Wrists neutral
  • No momentum

Breathing

Inhale during the lowering phase and exhale during the curl.

Tempo

3-1-2

Range of Motion

Lower bar until arms are nearly extended but elbows not locked; curl until forearms touch upper arms or bar level with shoulders.

Safety

Safety Notes

  • Avoid if acute elbow pain or injury
  • Use lighter weight to master form before progressing
  • Do not lock elbows to prevent joint stress
  • Warm up elbows and wrists first

Spotting

Spotting not typically needed; assist by stabilizing bar if form breaks on heavy sets.

Common Mistakes

  • Using too much weight and swinging
  • Hyperextending elbows at bottom
  • Allowing elbows to lift off pad
  • Gripping too tight causing wrist strain

When to Avoid

  • Elbow tendonitis
  • Wrist injuries
  • Shoulder impingement

Flexibility Needed

  • Wrist extension
  • Shoulder flexion

Build Up First

  • Basic standing curl form
  • Grip strength for barbell
