Exercise guide

EZ Barbell Standing Wrist Curl

  • Intermediate
  • Isolation
  • Rep-based

This isolation exercise targets the wrist flexors of the inner forearm, using the ergonomic curves of the EZ bar to reduce joint strain. It is highly effective for building forearm mass and improving grip strength through a concentrated range of motion.

Muscles worked

Primary

  • Forearms

Secondary

  • Biceps

Equipment

  • Ez barbell
  • Weight plate

Setup

  1. Stand with your feet shoulder-width apart and a slight bend in your knees for stability.
  2. Hold the EZ bar with an underhand (supinated) grip on the inner curves, palms facing forward.
  3. Let your arms hang fully extended in front of your thighs, keeping your shoulders pinned back and chest up.

How to do it

  1. Exhale as you curl the bar upward by flexing only your wrists toward your forearms, keeping your arms stationary.
  2. Squeeze your forearms at the top of the movement and hold the peak contraction for one second.
  3. Inhale as you slowly lower the bar back to the starting position using a controlled 2-second tempo.
  4. Ensure your elbows remain tucked against your sides and do not move throughout the repetition.

Form checklist

  • Keep your elbows locked in place; do not allow them to swing or assist the lift.
  • Ensure the movement comes strictly from the wrists, avoiding any bicep involvement.
  • Maintain a tall posture with a neutral spine and avoid leaning backward to cheat the weight up.
  • Use a full range of motion, allowing the wrists to fully extend at the bottom of each rep.

Pro tips

  • At the bottom of the rep, allow the bar to roll slightly down into your fingertips to maximize the stretch on the flexor muscles.
  • Focus on the mind-muscle connection by imagining you are trying to touch your palms to your inner forearms.

Make it harder

  • Implement a 3-4 second eccentric (lowering) phase to increase time under tension for the forearm flexors.
  • Perform a 10-second static hold at the top of the final rep of each set to exhaust the muscle fibers.
