Decision

Which should you choose?

The Cable Curl keeps constant tension on the muscle through the whole range of motion. The Dumbbell One Arm Prone Hammer Curl works each side independently and demands more stabilizer control. 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.

Choose based on your equipment and which movement you can progress consistently.

Can I do both the Cable Curl and the Dumbbell One Arm Prone Hammer Curl in the same program?
