Cable Unilateral Biceps Curl
The Single-Arm Cable Curl keeps constant tension on the biceps through the entire range. Training one arm at a time helps correct imbalances and improves mind–muscle connection because you can control elbow position and tempo more precisely. It’s widely used for hypertrophy to increase contraction quality and maintain smooth control on the way down.
Primary Equipment
Dual cable pulley machine

Key Benefits
- Constant cable tension improves biceps activation across the full range.
- Single-arm work helps correct left–right strength differences.
- Great for controlled tempo and strong contraction without needing heavy loads.
- Prepares you for Low Cable Curl (straight bar).
Instructions
- Stand next to the low pulley station, holding the handle with one hand.
- Keep your arm extended and your elbow close to your body.
- Bend the elbow, bringing the handle towards the shoulder.
- Contract your biceps at the top of the movement.
- Slowly return to the starting position and repeat before switching arms.
Tips
- Keep the elbow fixed to the side of the body throughout the movement.
- Avoid swinging the torso or using momentum.
- Focus on the bicep contraction on the way up.
- Slowly return to the starting position to maximize control and muscle activation.
Restrictions
Avoid if you have elbow pain or active forearm tendinitis. If you’ve had tendon issues, use lighter loads, slower tempo, and don’t aggressively lock out. Beginners and older adults should keep the range comfortable. If wrist discomfort appears, adjust the handle/grip and keep the wrist in line with the forearm. Persistent sharp pain means reduce load and range.
Common Mistakes to Avoid
- Twisting the torso to help the lift.
- Letting the elbow drift away and losing isolation.
- Letting the cable snap back without control.
