The cable seated overhead curl with an SZ bar is an upper-arm isolation exercise that targets the biceps. Performed seated with the cable set high and the bar curled in toward your head, it keeps constant tension on the biceps through the full range and uses the angled SZ (EZ) grip to ease strain on your wrists.

How to do the Cable Seated Overhead Curl (SZ Bar)

  1. 1Set the cable pulley to a high position and attach an SZ (EZ-curl) bar to the cable.
  2. 2Sit on a bench facing the machine with the cable running down to the bar in front of your face, and grip the angled sections of the bar with a shoulder-width underhand grip.
  3. 3Sit tall with your chest up, brace your core, and raise your upper arms so your elbows point forward and stay fixed in place.
  4. 4Curl the bar in toward the top of your head by bending only at the elbows, squeezing your biceps hard at the fully shortened position.
  5. 5Pause briefly at the top while keeping your upper arms still.
  6. 6Lower the bar under control back to the start until your elbows are extended, resisting the pull of the cable the whole way.
  7. 7Complete your reps, then return the bar to the stack with control.

Form tips

  • Keep your upper arms and elbows locked in one position so the work stays on the biceps and the movement comes only from your forearms.
  • Use the angled grip of the SZ bar to keep your wrists in a comfortable, neutral-leaning position rather than a hard supinated one.
  • Lower the bar slowly and resist the cable on the way out to make full use of the constant tension a cable provides.
  • Start lighter than you would for a standing curl, since the overhead angle puts the biceps in a fully stretched, less powerful position.

Common mistakes

  • Letting your elbows drift back or your upper arms swing, which turns the curl into a pulling motion and takes tension off the biceps.
  • Using too much weight and yanking the bar, which recruits momentum and the back instead of isolating the biceps.
  • Cutting the range short by not fully extending the elbows at the bottom, which loses the stretch and reduces the training effect.
  • Letting the wrists bend back under load, which strains the wrist and forearm tendons instead of loading the biceps.

Frequently asked questions

What muscles does the cable seated overhead curl with an SZ bar work?

It is an upper-arm isolation exercise that targets the biceps. The seated, overhead cable angle keeps tension on the biceps throughout the rep, and the SZ bar lets the forearms work at a wrist-friendly angle.

Why use an SZ (EZ) bar instead of a straight bar?

The SZ bar's angled grips let your wrists sit in a more neutral position, which reduces wrist and forearm strain compared with the fully supinated grip a straight bar forces.

How many sets and reps should I do?

As a biceps isolation move, 3–4 sets of 10–15 reps with a controlled tempo works well. Pick a weight you can curl without swinging your upper arms.

Where should I feel this exercise?

You should feel it in the biceps on the front of your upper arms, with a noticeable stretch at the bottom and a strong squeeze as you curl the bar toward your head.

Is the cable seated overhead curl good for beginners?

Yes. The seat and fixed cable line make it easier to keep your form strict, so beginners can isolate the biceps. Start light and focus on keeping your upper arms still.
