Alternating Hammer Curl: How-to, Tips & More

The Alternating Hammer Curl is a beginner isolation exercise for your brachialis. You do it with dumbbells, one side at a time. It is a good fit when your goal is both strength and muscle growth.

Besides the brachialis, it also works your biceps and brachioradialis, so it fits well in a session that trains those muscles together.
