Which should you choose?
The Barbell Drag Curl lets you load the heaviest weights and progress in small, steady jumps. The Biceps Leg Concentration Curl needs no equipment and scales through leverage, tempo and reps. If your gym has both options, neither is a wrong choice: pick the one that feels strongest through a full range, and swap after 6 to 8 weeks to keep the biceps adapting.
