What muscles does the Cable One-Arm Inner Biceps Curl work?

The Cable One-Arm Inner Biceps Curl primarily targets the biceps brachii, focusing on the inner head for peak development. While it’s mainly an isolation exercise, it also engages the forearm flexors for grip stability.

Is the Cable One-Arm Inner Biceps Curl suitable for beginners?

Yes, beginners can safely perform this exercise with light weight and proper form. However, it’s important to start slow, maintain elbow alignment, and avoid swinging the arm to prevent strain.

What equipment do I need for the Cable One-Arm Inner Biceps Curl, and are there alternatives?

You’ll need a cable machine with a single-handle attachment set at shoulder height. If a cable machine isn’t available, you can use a resistance band anchored at a similar height to mimic the movement.

How many sets and reps should I do for Cable One-Arm Inner Biceps Curl?

For strength and size, aim for 3–4 sets of 8–12 reps per arm. For endurance or toning, use lighter weight and perform 2–3 sets of 12–15 reps with controlled tempo.

What are common mistakes to avoid in the Cable One-Arm Inner Biceps Curl?

Avoid using your shoulder or back to lift the weight, as this reduces biceps activation. Also, do not jerk the cable; keep the movement slow and controlled to protect your joints and maximize muscle engagement.

Are there any safety tips for doing the Cable One-Arm Inner Biceps Curl?

Stand with a stable posture and keep your core engaged to prevent unnecessary strain on your lower back. Use an appropriate weight that allows controlled motion without overloading your elbow and shoulder joints.

What variations can I try for the Cable One-Arm Inner Biceps Curl?

You can perform the movement seated to eliminate body sway or use a rope attachment for a slightly different grip. Changing the cable height to low or high settings alters the angle of resistance and can emphasize different parts of the biceps.

How To Do

Stand sideways next to a cable machine with the handle set at shoulder height, arm extended out to the side and palm facing up. Keeping your elbow stationary, curl the handle toward your shoulder by contracting your biceps, then slowly lower back to the starting position. Maintain an upright torso and control the movement throughout.

Step-by-Step Instructions

Stand next to a cable machine with the handle attachment set at shoulder height.
Grab the handle with one hand, using an underhand (supinated) grip, and step slightly away from the machine to create tension in the cable.
Position your working arm extended out to the side, parallel to the floor, with your palm facing upward. Place your other hand on your hip for stability.
Keep your torso upright and your elbow stationary as you curl the handle toward your shoulder by contracting your biceps.
Squeeze your biceps at the top of the movement, ensuring full contraction.
Slowly lower the handle back to the starting position, fully extending your arm while maintaining control.
Repeat for the desired number of repetitions, then switch arms to work the other side.
