How to do the Barbell Wrist Curl

ForearmsBarbellIntermediate

The barbell wrist curl is one of the most direct and effective ways to build dense, powerful forearm flexors that support every pulling and gripping movement you train. Developing this often-neglected muscle group pays dividends in deadlifts, rows, and athletic performance alike.

Step-by-step

  1. Sit at the end of a bench, rest your forearms along your thighs with wrists just past your knees, and grip the barbell with palms facing up.
  2. Let the barbell roll down to your fingertips, achieving a full stretch at the bottom of each rep.
  3. Curl your fingers back around the bar and flex your wrists upward as high as range allows, squeezing hard at the top.
  4. Lower under control back to the stretched position and repeat without bouncing or using momentum.

Common mistakes

  • Cutting the range of motion short by skipping the finger-roll phase at the bottom, which eliminates the stretch and reduces muscle activation — allow the bar to roll to the fingertips every rep.
  • Lifting too heavy and compensating with elbow and upper body movement, which shifts load off the forearms — reduce the weight and anchor your forearms firmly to your thighs throughout the set.
  • Rushing through reps with no tempo control, which wastes time under tension — use a deliberate 2-second lowering phase to maximize forearm stimulus.

Pro tip — At the very top of each rep, pause for one full second and actively try to flex your forearm against the bar rather than just moving it through the motion — this mind-muscle connection dramatically increases fiber recruitment in the wrist flexors.
