Description
The Cable One Arm Curl is an effective isolation exercise performed on a cable machine with one hand, working the biceps independently. Performing it unilaterally allows each bicep to work separately, making it highly effective for correcting muscle imbalances. Thanks to the continuous cable tension, the biceps brachii remains under maximum activation throughout the movement. It can be performed with a palms-up (supinated), neutral, or even palms-down (reverse) grip, allowing you to target different muscle fibers. It also improves grip strength and arm concentration. When performed regularly, it provides significant improvements in bicep symmetry, hypertrophy, and arm detail development.
Step-by-Step Instructions
- 1
Attach a single handle to the low pulley of a cable machine.
- 2
Stand next to the cable machine, positioning yourself at a 90-degree angle to the machine.
- 3
Grasp the handle with one hand, palm facing up.
- 4
Keep your other hand on your hip or hold onto the machine for support.
- 5
Keep your upper arm stationary by your side, with your elbow close to your body.
- 6
Start with your arm fully extended.
- 7
Engage your core muscles.
- 8
Curl the handle upward by squeezing your bicep.
- 9
Maximally contract your bicep at the peak position.
- 10
Lower the handle back to the starting position in a controlled manner.
- 11
After completing the desired number of repetitions, switch to the other arm.
Key Points
- ✓Upper arm remains stationary, elbow close to the body.
- ✓Movement should only occur at the elbow joint.
- ✓Palms-up (supinated) grip.
- ✓Controlled tempo, do not use momentum.
- ✓Squeeze at the top of the movement.
Common Mistakes
- ✗Moving the upper arm - breaks isolation.
- ✗Swinging the body - uses momentum.
- ✗Choosing too heavy a weight - compromises form.
- ✗Letting the elbow drift from the side of the body - ruins the movement.
Breathing
Exhale as you curl upward, inhale as you lower the weight.
