How each one starts
Barbell Alternate Biceps Curl — first steps
- Stand up straight with your feet shoulder-width apart and hold a barbell in each hand, palms facing forward.
- Keep your upper arms stationary and exhale as you curl the weights while contracting your biceps.

- Adjust the cable machine so that the preacher curl pad is at chest height.
- Sit on the preacher curl bench and place your upper arms on the pad, gripping the cable attachment with an underhand grip.

Which should you choose?
The Barbell Alternate Biceps Curl lets you load the heaviest weights and progress in small, steady jumps. The Cable Preacher 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.
