How to do it
- Stand up straight with your feet shoulder-width apart and hold a barbell with an underhand grip, palms facing forward.
- Keep your elbows close to your torso and exhale as you curl the weights while contracting your biceps.
- Continue to raise the bar until your biceps are fully contracted and the bar is at shoulder level.
- Hold the contracted position for a brief pause as you squeeze your biceps.
- Inhale as you slowly begin to lower the bar back to the starting position.
- Repeat for the desired number of repetitions.

Sets and reps
Use an easy load and stop well before failure while you learn the movement.
Finish most sets with 1-3 good reps still available.
Use strict form and progress the load only after the top of the rep range is clean.
Common mistakes
- Adding load before the bar path is repeatable. Use a weight that lets every Barbell Curl rep follow the same controlled path.
- Shortening the range as fatigue builds. Use the largest pain-free range that keeps tension on your biceps.
- Turning the set into a speed contest. Pause briefly in the hardest position, then control the return instead of dropping into the next rep.
Barbell Curl FAQ
What muscles does the Barbell Curl work?
The primary target is biceps. It also involves forearms while you keep the movement controlled.
How many sets and reps should I do for the Barbell Curl?
Start with 3 sets in a repeatable range. Use 6-12 reps for most compound work or 10-15 for smaller isolation work, then add load after you can complete every rep cleanly.
How should I read the Barbell Curl strength standards?
Compare estimated one-rep max, not the weight from an arbitrary rep count. Buffro scales the published target to your bodyweight and sex.
