Dumbbell Seated Reverse Grip Concentration Curl

  • Intermediate
  • Isolation
  • Rep-based
  • Shoulders
  • Upper arms

This unilateral isolation exercise targets the brachialis and brachioradialis, building thickness in the upper arm and forearm while improving grip strength. The seated position and leg support eliminate momentum, ensuring the target muscles do all the work.

Setup

  1. Sit on the edge of a flat bench with your feet spread wider than shoulder-width apart.
  2. Hold a dumbbell in one hand using a pronated (overhand) grip, with your palm facing your body.
  3. Lean forward and brace the back of your upper arm, just above the elbow, against the inside of your same-side thigh.
  4. Extend your arm fully toward the floor, keeping a slight bend in the elbow to maintain tension.

How to do it

  1. Exhale and curl the dumbbell toward your shoulder by flexing the elbow, keeping your wrist firm and neutral.
  2. Squeeze the brachialis and forearm muscles at the peak of the contraction for one second.
  3. Inhale and slowly lower the weight back to the starting position using a controlled 3-second tempo.
  4. Complete the desired number of repetitions on one arm before switching to the other.

Form checklist

  • Keep the wrist straight and locked; do not let the weight pull your wrist into extension.
  • Ensure the elbow remains pinned against the inner thigh to prevent shoulder involvement.
  • Avoid using torso momentum or swinging the weight to complete the rep.
  • Maintain a flat back and engaged core to stabilize your upper body.

Pro tips

  • Grip the dumbbell as hard as possible throughout the set to maximize forearm recruitment and stability.
  • Focus on the 'mind-muscle connection' with the brachioradialis, the thick muscle on the thumb-side of your forearm.

Make it harder

  • Incorporate a 4-second eccentric phase to increase time under tension on the brachialis.
  • Add a brief pause at the midpoint of the lowering phase to challenge isometric strength.
