Exercise guide

EZ Barbell Standing Single Arm Neutral Wrist Curl

  • Intermediate
  • Isolation
  • Rep-based
  • Lower arms
  • Upper arms

This unilateral isolation exercise targets the brachioradialis and forearm extensors by using the unique angles of an EZ bar to provide a comfortable neutral grip. It is highly effective for building forearm thickness and improving grip stability without excessive wrist strain.

Equipment

  • Ez barbell

Setup

  1. Stand upright with your feet shoulder-width apart and a slight bend in your knees.
  2. Hold the EZ bar at the center of the inner 'V' curve with one hand using a neutral (hammer) grip.
  3. Let the arm hang naturally at your side with the elbow tucked firmly against your torso.
  4. Engage your core and keep your shoulders pinned back to maintain a stable base.

How to do it

  1. Exhale as you curl your wrist upward toward your forearm, keeping the rest of your arm completely stationary.
  2. Squeeze the forearm muscles at the top of the movement for a one-second pause.
  3. Inhale as you slowly lower the bar back to the starting position using a controlled 2-second tempo.
  4. Complete the full set of repetitions on one arm before switching to the other side.

Form checklist

  • Keep the elbow locked against your ribcage to prevent the bicep from taking over.
  • Ensure the movement occurs strictly at the wrist joint.
  • Avoid leaning your torso toward the weighted side to compensate for the load.
  • Maintain a firm grip on the bar throughout the entire range of motion.

Pro tips

  • Focus on the mind-muscle connection by imagining you are trying to touch the back of your hand to your forearm.
  • Use your non-working hand to lightly hold your working elbow in place if you struggle with arm swing.
  • Experiment with the different curves of the EZ bar to find the specific angle that provides the most tension in your brachioradialis.

Make it harder

  • Implement a 3-second eccentric (lowering) phase to increase time under tension.
  • Add a 'dead stop' at the bottom of each rep to remove momentum and force a stronger initial contraction.
