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 the dumbbells up, by bending at the elbow until the arms are fully flexed or as high as you can. As you do this keep your palms facing inwards the whole time.
Once done, return the dumbbells back down safely to your side. This is 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.
