How to Perform

Attach a straight or EZ bar to the low pulley of a cable machine and select your weight. Stand facing the machine with feet shoulder-width apart, grasp the bar with an overhand grip, and step back to create tension with arms extended.

  1. Keep elbows tucked to your sides and stationary.
  2. Curl the bar upward by flexing your elbows until forearms are vertical.
  3. Squeeze your forearms at the top for a brief pause.
  4. Slowly lower the bar back to full extension while resisting the cable.
  5. Maintain a straight back and neutral wrists throughout.

Coaching Tips

Form Cues

  • Elbows glued to sides
  • Squeeze forearms hard
  • Control the descent
  • Wrists stay neutral
  • No body swing

Breathing

Exhale as you curl the bar up and inhale as you lower it down; brace your core before each rep.

Tempo

3-0-2

Range of Motion

Start with arms fully extended and bar at thighs; curl until forearms are perpendicular to the floor or bar nears shoulders, then lower to full extension without locking elbows.

Safety

Safety Notes

  • Start with light weight to protect wrists and elbows
  • Avoid if you have acute wrist or elbow pain
  • Keep movements controlled to prevent strain
  • Ensure proper wrist flexibility before attempting
  • Stop immediately if sharp pain occurs

Spotting

Not typically required for this isolation exercise; use the machine's weight stack safeties or perform in a controlled environment.

Common Mistakes

  • Swinging the body for momentum
  • Flaring elbows outward
  • Bending wrists excessively
  • Rushing the eccentric phase
  • Using too much weight and losing form

When to Avoid

  • Wrist strain or tendonitis
  • Elbow joint issues
  • Recent forearm injury

Flexibility Needed

  • Adequate wrist extension and flexion
  • Shoulder flexion for arm positioning

Build Up First

  • Basic understanding of elbow flexion movements
  • Familiarity with cable machine use
