Description

An isolation exercise that targets the biceps, performed one arm at a time using a cable machine.

How to Do Cable One Arm Curl

  1. 1
    Setup

    Attach a D-handle to a low pulley cable machine. Stand facing the machine, grasp the handle with an underhand grip (palm up) in one hand.

  2. 2
    Setup

    Take a small step back to create tension, keeping your feet shoulder-width apart and your elbow tucked close to your side. Ensure your upper arm is stationary and perpendicular to the floor.

  3. 3

    Exhale and slowly curl the handle upwards towards your shoulder, contracting your bicep fully at the top of the movement. Keep your elbow fixed in place.

  4. 4

    Inhale and slowly lower the handle back to the starting position with control, fully extending your arm and feeling a stretch in your bicep.

  5. 5

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

Tips

  • Focus on keeping your upper arm completely still throughout the movement to isolate the bicep effectively, preventing any shoulder or back involvement.
  • Slightly supinate your wrist (rotate your palm upward) as you curl to maximize bicep activation, especially at the peak contraction.
  • Control both the concentric (lifting) and eccentric (lowering) phases of the curl to maximize time under tension and muscle engagement.
  • Avoid using momentum by bracing your core and preventing any rocking or swinging of your torso; let your bicep do all the work.

Common Mistakes

  • ×Swinging the arm or torso to lift the weight reduces bicep isolation; reduce the weight and focus on keeping your elbow tucked and upper arm stationary, using only your bicep to initiate the curl.
  • ×Not fully extending the arm at the bottom limits range of motion; allow a full stretch in the bicep at the bottom of the movement to ensure complete muscle activation, but stop just short of locking out the elbow.
  • ×Rushing the eccentric (lowering) phase diminishes muscle growth; control the weight on the way down, taking 2-3 seconds to lower the handle, which increases time under tension.
