Description

A resistance exercise that primarily targets the biceps using a cable machine, performed one arm at a time for improved focus on the muscle group.

How to Do Cable one arm inner biceps curl

  1. 1
    Setup

    Attach a D-handle to a low cable pulley. Stand facing the machine, slightly offset to the side of the cable stack.

  2. 2
    Setup

    Grab the handle with an underhand grip, palm facing up. Position your working elbow close to your side, slightly in front of your torso.

  3. 3

    Keeping your upper arm completely stationary, exhale and curl the handle upward towards your opposite shoulder, contracting your brachialis and biceps.

  4. 4

    Squeeze your bicep at the peak contraction, focusing on the inner head and brachialis activation.

  5. 5

    Slowly inhale and lower the handle back to the starting position with controlled movement, fully extending your arm to feel a stretch in the bicep.

  6. 6

    Complete all repetitions on one arm before switching to the other side.

Tips

  • To emphasize the inner bicep, slightly rotate your palm outward (supinate) as you curl, driving your pinky finger towards your shoulder.
  • Maintain constant tension by not fully resting the weight at the bottom; stop just short of full extension to keep the muscle engaged.
  • Keep your elbow fixed in position throughout the movement; avoid letting it drift forward or backward to ensure bicep isolation.
  • Focus on a strong mind-muscle connection, visualizing your brachialis and inner bicep contracting with each repetition.

Common Mistakes

  • ×Swinging the weight with your body or shoulder cheats the movement; keep your torso stable and elbow pinned to your side to isolate the bicep effectively.
  • ×Not fully extending the arm at the bottom limits the range of motion and muscle stretch; ensure a complete, controlled extension to maximize muscle fiber recruitment.
  • ×Letting the wrist flex or extend during the curl shifts tension away from the bicep; maintain a neutral, strong wrist position throughout the exercise.
