Barbell Standing Concentration Curl
- Intermediate
- Isolation
- Rep-based
- Lower arms
- Upper arms
This old-school isolation movement targets the biceps peak by using a bent-over position to eliminate momentum and maximize tension at the top of the contraction. It is highly effective for developing the long head of the biceps and improving mind-muscle connection.

Setup
- Stand with your feet shoulder-width apart and hold a barbell with a shoulder-width underhand (supinated) grip.
- Hinge forward at the hips until your torso is nearly parallel to the floor, maintaining a flat back and slight bend in the knees.
- Allow the barbell to hang directly beneath your shoulders so your arms are perpendicular to the floor.
How to do it
- Exhale and curl the barbell toward your forehead by hinging only at the elbows, keeping your upper arms completely stationary.
- Squeeze your biceps forcefully at the top of the movement for a one-second peak contraction.
- Inhale and slowly lower the barbell back to the starting position using a controlled three-second tempo.
- Ensure your arms reach full extension at the bottom before starting the next rep.
Form checklist
- Keep your upper arms vertical and still throughout the entire movement.
- Maintain a neutral spine and avoid rounding your lower back.
- Do not use your torso or legs to swing the weight up.
- Keep your wrists firm and avoid letting them curl excessively toward your forearms.
Pro tips
- Focus on 'dragging' the bar toward your chin rather than your chest to maximize the shortening of the biceps.
- Keep your elbows tucked in; letting them flare out shifts the load away from the biceps and onto the shoulders.
Make it harder
- Perform the exercise with an EZ-bar to allow for a more aggressive squeeze at the top without wrist discomfort.
- Add a 3-second isometric hold at the midpoint of the eccentric (lowering) phase to increase time under tension.
