1 arm palms down cable curl

One-Arm Palms Down Cable Curl – One of the most impactful things you could do with your arm workouts is to start including more curls using an overhand grip. They develop the neglected wrist extensors as part of your forearms, as well as a “shy” muscle called the coracobrachialis. You’d be surprised what would happen to your arms just by sprinkling in a few sets of curls at the end of your workouts using an overhand grip.

The one-arm cable variation allows you to keep your elbow in super tight to your body. This is often hard to do if you have a weak brachialis and coracobrachialis. If you do, you might compensate with more elbow flare when doing hammer and palms-down curls. Second, using the cable allows you to angle your grip to whatever degree feels most comfortable.
