Overview

The One-Arm Pronated Dumbbell Triceps Extension is a single-arm movement that targets the triceps to build strength while helping correct side-to-side differences. Using a pronated grip, with the palm facing forward, slightly changes the loading and adds more tension to the lateral and long heads of the triceps.

How to do it

  1. 1

    Setup and Starting Position

    • Lie on a bench and hold a dumbbell in one hand.
    • Use a pronated grip, with the palm facing forward.
    • Straighten your arm so the dumbbell sits above your shoulder.
    • Lock the elbow in place and keep the upper arm perpendicular to the floor.
  2. 2

    Execution

    • Bend the elbow to lower the dumbbell slowly toward the side of your head.
    • Let the forearm move while the elbow stays fixed.
    • Descend until you feel a deep stretch in your triceps.
    • Briefly pause, then straighten the arm to return to the start.
    • Perform 8 to 12 reps, then change arms. Do 3 to 4 sets.

Benefits

Enhances Triceps Strength and Definition: This exercise effectively isolates the triceps, promoting muscle growth and endurance.

Improves Muscle Balance and Stability: By training one arm at a time, it helps correct muscular imbalances and strengthens stabilizing muscles.

Increases Arm Control and Coordination: The pronated grip variation places additional emphasis on grip and wrist stability, improving overall arm function.

Reduces Strain on the Shoulder and Wrist: The unilateral movement allows for a natural range of motion, reducing the risk of injury compared to barbell movements.

Supports Pressing Movements: Strengthening the triceps helps improve performance in bench presses, overhead presses, and dips.
