The Dumbbell Hammer Curl is a strength-training exercise that primarily targets the brachialis and brachioradialis muscles in the upper arms, along with the biceps to a lesser extent. It is a variation of the traditional bicep curl that involves a neutral grip, resembling the grip you would use when holding a hammer.
Let's get started by grabbing both your dumbbells and have them hanging by your side with the palms facing inwards towards your body.
This is the starting position.
From here curl one of the dumbbells up, by bending at the elbow until the arm is fully flexed or as high as you can. As you do this keep your palm facing inwards throughout the full movement.
Once done, return the dumbbell back down safely to your side. Then repeat for the other arm. Once both are done you have done one repetition, now repeat this for the desired amount.
If you have limited gripping ability try using the Active Hands Gripping Aids to make this exercise as safe as possible.
