The cable unilateral bicep curl is a single-arm strength exercise that targets the biceps using a low cable pulley. Working one arm at a time lets you give each side full attention, fixing strength imbalances, and the cable keeps constant tension on the biceps through the whole range of motion.

Cómo hacer el Cable Unilateral Bicep Curl

  1. 1Attach a single handle to the low pulley of a cable machine and set the weight to a manageable load.
  2. 2Stand facing the machine, grip the handle with one hand in an underhand (palm-up) grip, and take a half step back so the cable stays taut.
  3. 3Set your feet about shoulder-width apart, brace your core, and keep your working-side elbow pinned close to your ribs.
  4. 4Curl the handle up toward your shoulder by bending only at the elbow, keeping your upper arm still.
  5. 5Squeeze the biceps hard at the top, with your forearm fully flexed and the handle near your shoulder.
  6. 6Lower the handle under control back to the start, resisting the pull until your arm is nearly straight.
  7. 7Complete all reps on one arm, then switch the handle to the other hand and repeat for an equal number of reps.

Consejos de técnica

  • Keep your elbow fixed against your side throughout the set so the biceps does the work rather than your shoulder swinging the weight up.
  • Lower the handle slowly over 2–3 seconds to take advantage of the constant cable tension and build more controlled strength.
  • Stand far enough back from the pulley that there is tension on the biceps even at the bottom of the rep.
  • Use your free hand on a fixed surface or your hip for balance, but don't let it help lift the weight.

Errores comunes

  • Swinging the torso or driving with the legs to heave the handle up, which shifts work off the biceps and strains the lower back.
  • Letting the elbow drift forward or away from the body, which turns the curl into a partial front-raise and reduces biceps tension.
  • Using a load too heavy to control, so the cable yanks the arm straight at the bottom and risks the elbow and shoulder.
  • Stopping short at the top instead of squeezing the biceps fully, leaving the most productive part of the rep undone.
  • Doing more reps on your stronger arm, which reinforces the very imbalance the unilateral curl is meant to fix.

Preguntas frecuentes

What muscles does the cable unilateral bicep curl work?

It mainly works the biceps of the working arm, with the forearm flexors helping to hold the handle and complete the curl. Training one arm at a time lets you focus the load on each biceps individually.

Why train one arm at a time instead of both together?

Working unilaterally lets you give each arm equal attention and even out strength imbalances. It also makes it harder to cheat, since you can't lean on a stronger side to help the weaker one.

How many sets and reps should I do?

For arm hypertrophy, 3–4 sets of 10–15 reps per arm is a solid range. Use a weight you can control through a full range of motion, keeping the same reps on both sides.

Why use a cable instead of a dumbbell for single-arm curls?

The cable keeps constant tension on the biceps through the entire movement, including the bottom of the rep where a dumbbell goes light. That steady resistance can be useful for building the mind-muscle connection.
