The bar close grip biceps curl is an upper-arm isolation exercise that builds the biceps brachii using a bar held with your hands close together. The narrow grip also recruits the brachialis and brachioradialis of the forearm as synergists, making it a simple way to add arm size and elbow-flexion strength.
How to do the Bar Close Grip Biceps Curl
- 1Stand tall with your feet about shoulder-width apart and your knees slightly soft.
- 2Grip the bar with an underhand (palms-up) grip, hands set close together near the center of the bar.
- 3Let the bar hang at arm's length against your thighs, with your elbows tucked close to your sides.
- 4Brace your core and keep your upper arms still as you curl the bar up toward your shoulders.
- 5Squeeze your biceps hard at the top, keeping your wrists straight and the bar under control.
- 6Lower the bar slowly back to the starting position, fully straightening your arms.
- 7Complete your reps, then set the bar down with control.
Form tips
- Keep your elbows pinned to your sides so the movement comes from your forearms rotating up, not your shoulders swinging.
- Lower the bar over two to three seconds to keep tension on the biceps through the full range.
- Keep your wrists neutral and stacked over your forearms rather than letting them bend back under the load.
- Stand with a tall chest and braced core so your lower back stays still throughout the set.
Common mistakes
- Swinging the torso or using momentum to heave the bar up, which shifts work off the biceps and strains the lower back.
- Letting the elbows drift forward as you curl, which turns the lift into a front-raise and reduces tension on the biceps.
- Cutting the range short by not fully straightening the arms at the bottom, which limits biceps stretch and growth.
- Bending the wrists back to muscle the weight up, which stresses the wrist joint and can cause forearm strain.
Frequently asked questions
What muscles does the bar close grip biceps curl work?
It primarily works the biceps brachii of the upper arm, with the brachialis and brachioradialis in the forearm assisting as synergists during elbow flexion.
How does a close grip change the curl?
Bringing your hands close together on the bar shifts a little more emphasis toward the outer head of the biceps and the brachioradialis, while a wider grip favors the inner head.
Is the bar close grip biceps curl good for beginners?
Yes. It is a simple, stable isolation move that teaches strict elbow flexion. Start with a light bar, keep your elbows tucked, and avoid swinging.
How many sets and reps should I do?
For arm size and strength, three to four sets of 8 to 12 controlled reps works well. Pick a load you can curl without swinging your torso.
