Exercise Description

Sit on a bench, lean forward, and hold a dumbbell with one hand. Rest your elbow on your inner thigh. Curl the weight up, squeezing your bicep, then lower slowly. Repeat.

How To Perform

Sit on a bench with your feet flat and legs slightly apart. Hold a dumbbell in one hand and lean forward slightly.

Place the working elbow against the inner thigh just above the knee to stabilize the upper arm.

Keeping the torso still, curl the dumbbell toward your shoulder by flexing at the elbow only, squeezing the biceps at the top.

Lower the dumbbell under control until the arm is nearly straight without locking the elbow, then repeat for reps before switching sides.

Expert Tips

Keep the elbow anchored - Maintain firm contact of the upper arm with the inner thigh to maximize isolation and reduce shoulder involvement.

Avoid swinging - Use a controlled tempo and keep the torso still to prevent momentum from taking over.

Prioritize form over load - Choose a weight that lets you move slowly and deliberately through the full range without compromising technique.

Use tempo or pauses - Add a brief squeeze at the top or a 2–3 second lower to increase time under tension and improve mind–muscle connection.

Common Mistakes

Using momentum - Swinging the weight reduces tension on the biceps and increases injury risk.

Elbow drifting - Allowing the elbow to move off the thigh reduces isolation and shortens the range of motion.

Too much weight - Excessive load compromises control and form, limiting stimulus to the target muscle.

Rushing the eccentric - Not lowering slowly misses key time under tension and reduces effectiveness.

Info – Dumbbell Concentration Curl

The Dumbbell Concentration Curl isolates the biceps by stabilizing the upper arm against the inner thigh. Keep movements smooth and controlled—avoid swinging or using body momentum. Ensure the elbow stays planted to maintain tension on the biceps. Choose a weight you can control through the full range, and increase load or reps gradually to progress. Variations like tempo changes and brief pauses can enhance mind–muscle connection and help break plateaus.
