Description

A seated exercise that isolates the biceps with the use of a cable machine.

How to Do Cable Seated One Arm Concentration Curl

  1. 1
    Setup

    Sit on a flat bench facing a low cable pulley, positioning your feet flat on the floor with knees bent. Adjust the bench so your working arm has a clear path for movement.

  2. 2
    Setup

    Grasp a D-handle attachment with an underhand grip (palm up) and rest the back of your upper arm (triceps) against the inside of your working thigh, just above the knee. Keep your elbow slightly bent.

  3. 3

    Exhale as you slowly curl the handle upwards towards your shoulder, contracting your biceps strongly. Keep your upper arm firmly pressed against your thigh and avoid any shoulder movement.

  4. 4

    Continue curling until your forearm is vertical or just past vertical, ensuring a full biceps contraction at the peak of the movement.

  5. 5

    Inhale as you slowly lower the handle back to the starting position with control, fully extending your arm without locking the elbow to maintain tension on the biceps.

Tips

  • Focus on squeezing your biceps at the top of the movement, holding the contraction for a brief moment to maximize muscle activation.
  • Keep your wrist straight and stable throughout the curl, avoiding any flexion or extension that can shift tension away from the biceps.
  • Control both the concentric (lifting) and eccentric (lowering) phases of the movement, taking 2-3 seconds for each to enhance time under tension.
  • Ensure your upper arm remains stationary against your thigh; this anchors the movement and prevents momentum from taking over.

Common Mistakes

  • ×Using momentum to lift the weight instead of muscle force will reduce biceps activation; fix this by slowing down the movement and ensuring only your forearm moves, with your upper arm anchored.
  • ×Allowing the elbow to lift off the thigh shifts tension away from the biceps; correct this by actively pressing your triceps into your thigh, ensuring strict isolation of the biceps.
  • ×Failing to fully extend the arm at the bottom of the movement limits range of motion; fully extend your arm without locking the elbow to achieve a complete stretch and maximize biceps development.
