Cable Bicep Curl

Muscles Cable Bicep Curl Works

Muscles used

• Bicepsfront of the upper arms
• Brachialisdeep muscle under the biceps near the elbow
• Brachioradialisouter forearm muscle running from the elbow toward the thumb side of the wrist
• Coremuscles around the abs, lower back, and pelvis

Main muscleHold the cable bar and curl it toward your shoulders while keeping your elbows by your sides. The main muscle driving this movement is your biceps. Your biceps bend your elbows against constant cable tension.

Supporting musclesYour brachialis adds elbow-flexion strength, your brachioradialis assists from the forearm, and your core keeps your torso from leaning back.

How it should feelThe cable should keep tension on your biceps as you lift and lower. At the top, the front of your upper arms should feel short and tight.

Signs you're offIf your torso leans back or your elbows drift forward, you are using momentum and shoulders instead of biceps. If your wrists bend, tension can leak away.

Remember thisKeep your elbows tucked and curl by folding your forearms up with your biceps.
