The barbell spider curl is an isolation exercise for the biceps, performed lying face-down on an incline bench with your arms hanging straight toward the floor. This position keeps the biceps under tension through the whole range and removes the body swing of a standing curl, making it a strict, focused builder of the upper arms.

Cómo hacer el Barbell Spider Curl

  1. 1Set an incline bench to roughly 45° and lie face-down on it so your chest is supported and your arms hang freely off the top edge.
  2. 2Reach down and take a shoulder-width, underhand (supinated) grip on the barbell, letting your arms hang straight toward the floor.
  3. 3Brace your core and keep your upper arms vertical and still, pointing straight down throughout the set.
  4. 4Curl the bar up toward your shoulders by flexing your biceps, keeping your elbows fixed in place.
  5. 5Squeeze the biceps hard at the top, where your forearms are roughly vertical.
  6. 6Lower the bar under control back to a full stretch at the bottom, 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 perpendicular to the floor and motionless — the only movement should come from your elbows.
  • Use a controlled tempo and a deliberate lowering phase; the strict, supported position rewards slower reps over heavy momentum.
  • Let your arms fully straighten at the bottom of each rep to train the biceps through a complete stretch.
  • Pick a lighter load than you would for standing curls, since the chest support strips away any chance to swing the weight up.

Errores comunes

  • Swinging the elbows forward or back to heave the bar up, which shifts the work off the biceps and defeats the strict design of the movement.
  • Using too much weight and only completing half reps, which cuts the tension on the biceps short at both the stretch and the squeeze.
  • Dropping the bar quickly instead of lowering it under control, throwing away the lengthening phase where much of the muscle work happens.
  • Lifting the chest off the bench to recruit the back and shoulders, turning a strict curl into a cheat rep.

Preguntas frecuentes

What muscles does the barbell spider curl work?

It is an isolation exercise for the biceps of the upper arms. The face-down incline position keeps the biceps under constant tension and minimizes help from other muscles.

How is the spider curl different from a regular barbell curl?

You lie face-down on an incline bench with your arms hanging straight down, which prevents the body swing of a standing curl and keeps the biceps loaded through the full range.

Is the barbell spider curl good for beginners?

Yes. The supported position makes it hard to cheat, so it teaches strict form. Start light to groove the movement before adding weight.

How many sets and reps should I do?

As a biceps isolation move, 3–4 sets of 10–15 controlled reps works well. Prioritize a full stretch and squeeze over heavier loads.
