The EZ barbell spider curl is an isolation exercise that targets the biceps brachii, with help from the brachialis and brachioradialis. Performed with your chest braced against the upright pad of an incline bench so the arms hang straight down, it removes momentum and keeps constant tension on the biceps through every rep.

Cómo hacer el EZ Barbell Spider Curl

  1. 1Set an incline bench to roughly 45° and lie chest-down against the pad with your feet planted for balance.
  2. 2Take an EZ barbell with an underhand grip on the inner angled sections, hands a little narrower than shoulder-width to keep the wrists comfortable.
  3. 3Let your arms hang straight down from your shoulders, fully extended, with the bar just clear of the floor.
  4. 4Keeping your upper arms vertical and still, curl the bar up by flexing at the elbows until your forearms are near vertical.
  5. 5Squeeze the biceps hard at the top while keeping your wrists neutral.
  6. 6Lower the bar under control back to full extension, resisting the weight the whole way down.
  7. 7Complete your reps, then set the bar down safely on the floor or a rack.

Consejos de técnica

  • Keep your upper arms pointing straight at the floor and locked in place — only the forearms should move.
  • Use the angled grip of the EZ bar to keep your wrists in a neutral, pain-free position throughout the set.
  • Pause briefly at full extension each rep so you start from a dead stop and can't use momentum.
  • Pick a moderate weight you can control on the way down — the strict position rewards tension over load.

Errores comunes

  • Swinging the upper arms forward to heave the bar up, which shifts work off the biceps and defeats the strict setup.
  • Cutting the lowering phase short, which loses the constant tension that makes the spider curl effective.
  • Going too heavy and only doing partial reps, reducing the range of motion and the stretch on the biceps.
  • Letting the wrists curl or bend backward instead of staying neutral, which strains the wrist and forearm.

Preguntas frecuentes

What muscles does the EZ barbell spider curl work?

It primarily works the biceps brachii, with the brachialis and brachioradialis assisting as synergists. The chest-down position isolates the biceps by preventing momentum.

What's the difference between a spider curl and a preacher curl?

In a spider curl your arms hang straight down from the vertical bench pad, so tension peaks near the top of the rep. A preacher curl uses an angled pad that supports the arms and challenges the muscle more in the stretched, lower position.

Why use an EZ bar instead of a straight bar?

The EZ bar's angled grips let your wrists sit in a more neutral position, which is easier on the wrists and elbows than the fully supinated grip of a straight bar.

How many sets and reps should I do?

As an isolation move, the spider curl responds well to 3–4 sets of 10–15 reps with a moderate, controlled weight. Focus on a strong squeeze and a slow lowering phase rather than heavy loads.
