Preacher Curl Machine

Muscles Preacher Curl Machine 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
• Rotator cuffsmall muscles that stabilize the shoulder joint

Main muscleRest your arms on the pad and curl the handle or bar toward your shoulders. The main muscle driving this movement is your biceps. Your biceps contract to bend your elbows and lift the handle.

Supporting musclesYour brachialis helps with elbow flexion, and your brachioradialis assists from the outer forearm.

How it should feelAs you curl the handle up, the front of your upper arms should shorten and squeeze. The pad should make the biceps work feel more isolated.

Signs you're offIf your arms lift off the pad or your shoulders shrug, you are losing biceps isolation. If your wrists bend, your wrists and elbows may take extra stress.

Remember thisKeep your arms on the pad and curl the handle by squeezing your biceps.
