Which should you choose?
The Barbell Reverse Preacher Curl lets you load the heaviest weights and progress in small, steady jumps. The Cable One Arm Curl keeps constant tension on the muscle through the whole range of motion. 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.
