Cable Reverse One Arm Curl

A reverse grip on a one-arm cable curl trains the brachialis and forearm more than the biceps directly, and doing it one arm at a time makes any strength imbalance between sides obvious. Because reverse-grip curls use less weight than a standard curl, ego needs to stay in check here — going too heavy just turns it into a wrist curl in disguise. It's a solid forearm-building accessory for anyone chasing grip strength.

How to Do the Cable Reverse One Arm Curl

1. Stand facing a cable machine with your feet shoulder-width apart.
2. Grip the cable handle with an underhand grip, palm facing down.
3. Keep your elbow close to your side and slowly curl your forearm up toward your shoulder.
4. Pause briefly at the top, then slowly lower your forearm back down to the starting position.
5. Perform the set reps for your first side, then mirror the movement on your opposite side with equal focus.

Technique & Form Tips

Perform flexion at the elbow while keeping your setup steady and supported. Maintain the specific elbow placement demonstrated for your chosen variation, such as preacher, incline, or hammer curl, to ensure consistent mechanical load through the arc.

Common Mistakes to Avoid

• Using hip momentum: Keep your torso stable to prevent swinging the load upward with your lower body.
• Drifting elbows: Maintain the elbow position relative to your body as defined by your specific curl variant.
• Lack of eccentric control: Lower the weight under control rather than letting it fall.

How to Breathe During This Exercise

Breathe steadily throughout the movement, ideally exhaling during the contraction phase.

Comfort and Control

Choose a load and range you can control. Stop if the movement causes pain. If discomfort persists, stop and ask a qualified professional about an appropriate exercise and range.

General guidance: Mayo Clinic on weight-training technique. Follow the specific movement steps above for this variation.
