The cable biceps curl with an SZ-bar (EZ-bar) is an isolation exercise that targets the biceps brachii, with assistance from the brachialis and brachioradialis of the forearm. The angled bar lets you curl in a semi-supinated grip that is easier on the wrists, while the low cable pulley keeps constant tension on the muscle through the full range.
Cómo hacer el Cable Biceps Curl (SZ-bar)
- 1Attach an SZ-bar (EZ-bar) to a low pulley and stand facing the cable stack, about one stride back so the cable stays taut.
- 2Grip the angled sections of the bar with palms facing up and your hands roughly shoulder-width apart.
- 3Stand tall with your knees soft, brace your core, and pin your elbows to the sides of your torso.
- 4Curl the bar up toward your shoulders by bending only at the elbows, keeping your upper arms still.
- 5Squeeze your biceps hard at the top, holding for a moment without letting your elbows drift forward.
- 6Lower the bar under control back to full extension, resisting the cable on the way down.
- 7Complete your reps, then step in to return the weight to the stack with control.
Consejos de técnica
- Keep your elbows fixed against your sides so the movement stays at the elbow and the tension stays on the biceps.
- Use the angled grip of the SZ-bar to keep your wrists in a comfortable semi-supinated position and avoid wrist strain.
- Control the lowering phase for two to three seconds — the constant cable tension makes the negative especially effective.
- Stand far enough from the stack that the cable line of pull stays taut even at the bottom of the rep.
Errores comunes
- Swinging the torso or using momentum to throw the bar up, which shifts work off the biceps and strains the lower back.
- Letting the elbows drift forward at the top, which turns the curl into a front-raise and reduces biceps tension.
- Cutting the range short by not fully extending at the bottom, which loses the stretched portion where the cable keeps you loaded.
- Bending the wrists back toward the forearms instead of keeping them neutral, which puts unnecessary stress on the wrist joint.
Preguntas frecuentes
What muscles does the cable biceps curl with an SZ-bar work?
It primarily targets the biceps brachii, with the brachialis and brachioradialis of the upper arm and forearm assisting as synergists.
Why use an SZ-bar instead of a straight bar?
The SZ-bar (EZ-bar) has angled grips that let you hold a semi-supinated position, which is easier on the wrists and elbows than the fully supinated grip of a straight bar.
What's the benefit of using a cable instead of dumbbells?
The cable keeps constant tension on the biceps throughout the entire rep, including the stretched bottom position where free weights lose resistance.
How many sets and reps should I do?
For biceps growth, 3 to 4 sets of 10 to 15 reps with controlled tempo works well, since this is an isolation movement that responds to moderate loads and good form.
Is the cable SZ-bar curl good for beginners?
Yes. The cable's fixed line of pull and the SZ-bar's wrist-friendly grip make it easy to learn good curl form, making it a solid choice for beginners.
