Dumbbell Standing Concentration Curl

  • Intermediate
  • Isolation

The standing concentration curl is a unilateral isolation movement that emphasizes the bicep peak by using the inner thigh to eliminate momentum. It provides a high degree of stability, allowing for maximum motor unit recruitment in the biceps brachii.

Setup

  1. Stand with your feet wider than shoulder-width apart and hinge forward at the hips until your torso is nearly parallel to the floor.
  2. Hold a dumbbell in one hand and brace your free hand on the opposite knee for support.
  3. Press the back of your upper arm (triceps) firmly against the inside of your thigh on the same side.
  4. Let the dumbbell hang at full arm extension with your palm facing forward.

How to do it

  1. Exhale as you curl the weight toward your shoulder, keeping your upper arm pinned against your thigh to prevent any swinging.
  2. Squeeze your bicep forcefully at the top of the movement for a one-second pause.
  3. Inhale as you slowly lower the dumbbell back to the starting position over a 3-second count.
  4. Perform the desired number of repetitions on one arm before switching to the other.

Form checklist

  • Keep your torso still; do not rock your body to help lift the weight.
  • Ensure the elbow remains tucked against the inner thigh throughout the entire set.
  • Achieve a full stretch at the bottom without locking out the elbow aggressively.
  • Keep your wrist firm and avoid letting it 'flop' backward during the curl.

Pro tips

  • At the top of the rep, rotate your wrist so your pinky finger points toward your shoulder to maximize bicep supination.
  • Focus on the mind-muscle connection by imagining you are trying to touch your forearm to your bicep.

Make it harder

  • Incorporate a 3-second pause at the peak of the contraction to increase time under tension.
  • Use a 'fat grip' or wrap a towel around the handle to increase forearm and grip demand.
