How to do the Cable Seated Curl
BicepsCableBeginner
The cable seated curl delivers constant tension through every degree of the movement, making it one of the most effective tools for building thick, full biceps. Master the mechanics here and you will lay down a foundation of arm strength that carries into every pull you ever do.

Step-by-step
- Sit facing the cable stack with your feet flat on the floor, grasp the straight or EZ bar with a supinated grip at shoulder width, and brace your core.
- Pin your elbows to your sides and keep them stationary as you curl the handle up toward your chin in a smooth controlled arc.
- Squeeze your biceps hard at the top for a full one-second contraction before beginning the descent.
- Lower the weight slowly over two to three seconds, letting your arms extend fully at the bottom to maximize the stretch under load.
Common mistakes
- Letting the elbows drift forward as the weight rises, which shifts stress onto the front deltoids — keep elbows locked at your sides throughout the entire rep.
- Using momentum by rocking the torso back at the start of each rep, which bleeds tension away from the biceps — sit tall and initiate every rep with muscle, not movement.
- Cutting the range of motion short at the bottom, which skips the stretched position where cable tension is highest — allow full elbow extension on every single rep.
Pro tip — Actively supinate your wrists outward as you curl, rotating your pinkies up and toward your shoulders at the top, to fully engage the short head and peak the contraction beyond what a simple flex alone produces.
