Spider curl

Log this in the tracker

A curl leaning face down on an incline bench, strict through the top half.

What it is

You lie chest-down on an incline bench with the arms hanging straight below the shoulders. The position removes any swing and keeps constant tension in the shortened range.

Muscles worked

Primary: Biceps. Secondary: Brachialis.

How to perform it

  1. Set a bench to about forty-five degrees and lie face down with the chest on the pad.
  2. Let the arms hang straight down with a dumbbell in each hand or an EZ bar.
  3. Curl up toward the shoulders, squeezing hard at the top.
  4. Lower under control until the arms are fully straight.

Common form faults

  • Elbows drifting back to bring the shoulders into the lift. Keep the upper arms hanging vertically; only the forearms move.
  • Chest lifting off the pad at the top. Stay pinned to the bench. If you have to lift, the load is too heavy.

Programming

10 to 15 reps with a squeeze at the top. A natural partner to the incline curl, which loads the stretch instead.

Variations & substitutions

Frequently asked questions

Spider curl or preacher curl?
Both hold the upper arm still. The spider curl keeps tension high at the top; the preacher loads the bottom more. Rotate between them.
Dumbbells or EZ bar?
An EZ bar is easier to load and kinder on the wrists; dumbbells let each arm work independently and allow a supinating twist.
