How each one starts
Barbell Seated Close-Grip Concentration Curl — first steps
- Sit on a bench with your feet flat on the floor and hold a barbell with an underhand grip, hands shoulder-width apart.
- Rest your upper arms against your inner thighs, just above your knees, and let the barbell hang down in front of you.

Which should you choose?
The Barbell Seated Close-Grip Concentration Curl lets you load the heaviest weights and progress in small, steady jumps. The Cable Seated 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.
