Dumbbell Cross-body Hammer Curl (Biceps, Brachialis, and Brachioradialis) | Exercise Guides and Videos

The dumbbell cross-body hammer curl is an excellent isolation exercise for the bicep, brachialis, and brachioradialis muscles. Now, this is a great exercise for anyone as it’s very simple to do and the results speak for themselves, so it’s recommended to include this exercise in every arm routine for maximum gains.

But, starting light is highly recommended before progressing to heavier weights with this exercise since the biceps is a vulnerable muscle under heavy resistance loads.

So, make sure to use proper form while training to reap the best results possible.
