Dumbbell Concentration Curl
DumbbellUnilateralStrength
The Dumbbell Concentration Curl is a targeted isolation exercise performed seated with one arm resting on the inner thigh, curling a dumbbell toward the shoulder while keeping the upper arm stationary to maximize biceps contraction. Its primary purpose is to build biceps strength and peak size by minimizing momentum and emphasizing the muscle's peak contraction. It benefits bodybuilders, arm-focused athletes, and anyone seeking improved elbow flexion power, requiring only a dumbbell and bench.
How to Perform Dumbbell Concentration Curl
- 1Sit on the edge of a flat bench with feet flat on the floor, shoulder-width apart, and knees bent at 90 degrees.
- 2Select a dumbbell and hold it in one hand with a supinated grip (palm facing up), arm fully extended hanging between your legs.
- 3Rest your upper arm against the inside of your opposite thigh, elbow pointing down and lightly touching the thigh for support.
- 4Keep your back straight, chest up, and core engaged; lean slightly forward from the hips to secure the arm position.
- 5Inhale, then exhale as you curl the dumbbell toward your shoulder by flexing your elbow, keeping your upper arm stationary and squeezing your bicep at the top.
- 6Pause briefly at the top (1 second), then inhale as you slowly lower the dumbbell back to the starting position with control.
- 7Complete all reps for one arm, then switch to the other arm.
- 8Key form tips: Avoid swinging or using momentum—motion should come only from the elbow. Keep elbow pinned to thigh throughout. Common mistakes: Using too much weight leading to shoulder involvement or incomplete range of motion.
