Cable Curl
Muscles worked
Instructions
- 1Stand up with your torso upright while holding a cable curl bar that is attached to a low pulley. Grab the cable bar at shoulder width and keep the elbows close to the torso. The palm of your hands should be facing up (supinated grip). This will be your starting position.
- 2While holding the upper arms stationary, curl the weights while contracting the biceps as you breathe out. Only the forearms should move. Continue the movement until your biceps are fully contracted and the bar is at shoulder level. Hold the contracted position for a second as you squeeze the muscle.
- 3Slowly begin to bring the curl bar back to starting position as your breathe in.
- 4Repeat for the recommended amount of repetitions.

About Cable Curl
The low-pulley cable curl isolates the biceps while keeping constant tension from start to finish. Unlike dumbbells, the cable never lets the load off at the bottom, which increases time under tension — an asset for pump and hypertrophy. Standing facing the pulley, elbows fixed by your sides, you raise the handle in supination then brake the descent. It is an excellent finisher at the end of a session, or a way to keep tension when dumbbells become too easy at the bottom of the range.

warningCommon mistakes
- warningLeaning the torso back to assist with the body
- warningLetting the weight drop too quickly
- warningPushing the elbows forward at the end of the curl
- warningUsing too heavy a stack that breaks the isolation
- warningStanding too close to the pulley, which reduces tension at the start of the movement
tuneVariations and alternatives
- tuneOne-arm cable curl – unilateral work that isolates each biceps further.
- tuneCable hammer curl – neutral grip that also engages the brachialis and forearm.
- tuneStanding high-pulley cable curl – reversed pulling angle, arms rising toward the ears.
- tuneBarbell curl – a base movement that allows heavier loading with slight, controlled momentum.
person_checkWho it's for and level
The cable curl suits every level, from the beginner learning the curl's bar path thanks to the cable's guidance, to the experienced lifter looking to keep tension on the biceps where dumbbells lose it at the bottom. It's particularly useful at the end of a session to chase extra pump, or to vary the stimulus after heavier free-weight movements.
shieldSafety and precautions
Always keep your elbows fixed close to your body to avoid shifting the effort onto the shoulders or back. Avoid leaning the torso back to help lift the weight, a habit that increases lower-back stress without benefiting the biceps. Choose a load that lets you control the descent all the way down; too heavy a load shortens the range and reduces the exercise's effectiveness.
calendar_monthWhere to place it in your program
Place the cable curl as the 2nd or 3rd exercise in a biceps session, after a heavier base movement like the barbell curl, for 3 sets of 10 to 15 reps. It also works very well at the end of a back session, to finish off the biceps indirectly worked by pulling movements. Two sessions a week are enough to progress without excess fatigue on the elbow joint.
helpFrequently asked questions
Is the cable curl better than the dumbbell curl?
It offers more constant tension, while dumbbells allow heavier loading; the two complement each other well.
Which handle should I use for the cable curl?
A straight or EZ bar to work both arms, or a single handle for more precise unilateral training.
Cable curl with one or two arms?
Both work. With one arm (unilateral pulley) you isolate each biceps better and fix imbalances; with two arms on a bar you can load a bit heavier.
How many sets and reps?
3 sets of 10 to 15 reps suit this isolation exercise well.
Is the cable curl beginner-friendly?
Yes, the cable's guided path makes it easier to learn a good curling motion.
Where should I place the cable curl in my session?
At the end of a biceps session, after heavier base movements like the barbell or dumbbell curl.
What's the difference between a low and high pulley for a curl?
The low pulley is the classic setup; a high pulley (between two pulleys) changes the pulling angle upward.
Should I lock out the elbows at the bottom?
No, keep a slight bend at the bottom to preserve tension on the biceps and protect the joint.
Does the cable curl engage the forearm?
A little for stabilization, but much less than hammer curls, which specifically target the brachioradialis.
Can I superset the cable curl with a triceps exercise?
Yes, it's a classic combination for an arm superset, alternating biceps and triceps without rest.
Is a low pulley essential?
Yes for the classic version; without one, substitute a dumbbell or barbell curl while keeping the same volume.
Should I change the handle regularly?
Not required, but occasionally varying it (EZ bar, single handle) helps maintain progress and avoids monotony.
Is the cable curl suitable for people with wrist pain?
Often better tolerated than a straight bar thanks to the handle's free path, but try an EZ attachment if discomfort persists.
Is the cable curl suitable for training to failure?
Yes, the cable's guided path keeps the end of the set safe, making it a good choice for pushing to failure without risking loss of control over the weight.
