Reverse SZ-Bar Curl Guide: Build Bigger Forearms

Learn how to master the Reverse SZ-Bar Curl to increase forearm thickness, improve grip strength, and balance your arm development with professional form tips.

How to Perform

  1. Stand upright with your feet shoulder-width apart and grasp the SZ-bar using a shoulder-width overhand grip.
  2. Rest the bar against your thighs with your elbows tucked firmly against your ribs and a slight bend in your knees.
  3. Exhale and curl the bar toward your shoulders by flexing your elbows while keeping your wrists straight and locked.
  4. Continue the movement until your forearms reach a vertical position, ensuring your elbows do not drift forward.
  5. Squeeze your forearms at the peak of the movement for a one-second pause to maximize muscle tension.
  6. Inhale and slowly lower the bar back to the starting position along the same arc to maintain constant control.

Common Mistakes

  • Using momentum or swinging the torso to lift the weight
  • Allowing the elbows to flare out away from the body
  • Letting the wrists collapse or bend during the upward phase
