Exercise guide

Barbell Reverse Curl

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

The Barbell Reverse Curl targets the brachialis and brachioradialis, helping to build forearm thickness and improve grip strength while adding width to the upper arm. By using a pronated (overhand) grip, you shift the emphasis away from the biceps brachii and onto the muscles of the outer arm and forearm.

Equipment

  • Barbell

Setup

  1. Stand upright with your feet shoulder-width apart and a slight bend in your knees.
  2. Grasp the barbell with a shoulder-width, pronated (overhand) grip, palms facing your thighs.
  3. Pull your shoulders back and down, and tuck your elbows tightly against your ribcage.

How to do it

  1. Exhale as you curl the bar toward your shoulders by hinging only at the elbows, keeping your wrists straight and firm.
  2. Squeeze your forearms and upper arms at the top of the movement for a one-second pause.
  3. Inhale as you slowly lower the barbell back to the starting position using a controlled 2-3 second tempo.
  4. Maintain a full range of motion, stopping just before your elbows lock out at the bottom.

Form checklist

  • Keep elbows pinned to your sides; do not let them drift forward.
  • Maintain a neutral wrist position; do not let the wrists 'flop' or bend backward.
  • Avoid using momentum or swinging your torso to lift the weight.
  • Keep your core engaged and back straight throughout the set.

Pro tips

  • Try a thumbless grip to further isolate the brachioradialis and reduce the contribution of the hand flexors.
  • Focus on 'pushing' the back of your hands toward the ceiling to maximize the tension on the top of the forearm.

Make it harder

  • Implement a 4-second eccentric (lowering) phase to increase time under tension for the forearm muscles.
  • Use a thick bar or 'fat grips' to significantly increase the demand on your grip strength.
