The EZ barbell spider curl is an upper-arm isolation exercise that targets the biceps brachii and brachialis, with the brachioradialis assisting. Performed lying chest-down over the steep side of a preacher bench so the arms hang straight down, it removes momentum and keeps constant tension on the biceps through the whole curl.
Cómo hacer el EZ Barbell Spider Curl
- 1Set an incline or preacher bench so its vertical side faces you, and load the EZ bar on the floor in front of it.
- 2Lie chest-down on the bench with your shoulders over the top edge and your feet planted for stability.
- 3Reach down and grip the EZ bar on its inner angled grips, palms facing up, with your arms hanging straight toward the floor.
- 4Brace your core and let your upper arms hang perpendicular to the floor, keeping your elbows close to your sides.
- 5Curl the bar up toward your forehead by contracting your biceps, keeping your upper arms still and only moving at the elbow.
- 6Squeeze your biceps hard at the top, holding the contracted position for a brief moment.
- 7Lower the bar under control until your arms are fully extended and hanging straight down again.
- 8Complete your reps, then set the bar back down on the floor under control.
Consejos de técnica
- Use the EZ bar's angled grips to keep your wrists in a neutral, semi-pronated position and reduce strain on the wrists and forearms.
- Keep your upper arms vertical and motionless so the biceps do the work instead of your shoulders swinging the weight.
- Lower the bar slowly over 2–3 seconds to maximize time under tension and biceps growth.
- Pause and squeeze at the top of each rep to reinforce the peak contraction rather than rushing the lift.
Errores comunes
- Swinging the upper arms or rocking the body to heave the bar up, which shifts tension off the biceps and uses momentum instead of muscle.
- Using too much weight and only completing partial reps, which shortens the range of motion and limits biceps development.
- Dropping the bar quickly on the way down, wasting the eccentric portion where much of the muscle-building stimulus comes from.
- Letting the wrists bend backward under load instead of keeping them firm, which strains the wrists and forearms.
Preguntas frecuentes
What muscles does the EZ barbell spider curl work?
It targets the biceps brachii and brachialis as the primary movers, with the brachioradialis in the forearm assisting. The spider position removes momentum so the biceps stay under constant tension.
Why use an EZ bar instead of a straight bar for spider curls?
The EZ bar's angled grips put your wrists in a semi-pronated position, which is more comfortable and reduces wrist and forearm strain while still loading the biceps effectively.
How is the spider curl different from a preacher curl?
In a spider curl you lie chest-down so your arms hang straight down vertically, keeping tension constant across the whole range. A preacher curl rests your arms on an angled pad, which eases tension near the top.
How many sets and reps should I do?
As an isolation move, 3–4 sets of 10–15 reps with a controlled tempo works well. Use a weight you can curl with strict form and no swinging.
