Description

A dumbbell concentration curl is an exercise focusing on the biceps. It is performed while sitting, with the upper body bent forward, and the elbow of the arm performing the exercise is supported on the same side's inner thigh.

How to Do Dumbbell Concentration Curl

  1. 1
    Setup

    Sit on a flat bench with your feet spread wide, planting them firmly on the floor. Grab a dumbbell with an underhand grip (palm facing up) in one hand.

  2. 2
    Setup

    Lean forward slightly from your hips, allowing your working arm to hang between your legs. Rest the back of your upper arm or elbow firmly against the inner thigh of the same side.

  3. 3
    Setup

    Ensure your arm is fully extended with the dumbbell hanging towards the floor, maintaining a slight bend in the elbow to prevent hyperextension.

  4. 4

    Exhale as you slowly curl the dumbbell upwards towards your shoulder, contracting your brachialis and biceps. Keep your upper arm stationary against your thigh throughout the movement.

  5. 5

    Squeeze your bicep hard at the top of the movement when the dumbbell is near shoulder level, ensuring peak contraction. Your wrist should remain neutral or slightly extended.

  6. 6

    Inhale as you slowly lower the dumbbell back to the starting position with control, fully extending your arm while maintaining tension in the working muscle.

Tips

  • Maintain constant tension throughout the set by not fully relaxing your arm at the bottom or top, keeping the muscle under load.
  • Focus intently on the mind-muscle connection, visualizing your brachialis and biceps contracting and extending with each repetition.
  • Keep your wrist straight and avoid flexing or extending it excessively, as this can shift tension away from the target muscles and onto your forearms.
  • Perform the eccentric (lowering) phase slowly, taking 2-3 seconds to return the dumbbell to the starting position to maximize muscle damage and growth.

Common Mistakes

  • ×Swinging the weight or using momentum reduces muscle isolation; reduce the weight and focus on a slow, controlled movement.
  • ×Lifting your elbow off your inner thigh compromises stability and isolation; ensure your upper arm remains pressed firmly against your thigh throughout the curl.
  • ×Not achieving a full range of motion by stopping short at the bottom or top limits muscle activation; ensure a complete arm extension and a full contraction at the peak.
