Hammer curls primarily work the biceps, specifically targeting the long head of the biceps brachii, the brachialis, and the brachioradialis, which is a key forearm muscle. This exercise is a variation of the traditional bicep curl, and it also helps in building forearm and grip strength. Hammer curls are considered an isolation exercise, focusing on the bicep muscles, and they are beneficial for developing grip strength and wrist stability. Additionally, they mimic natural movement patterns, making everyday activities such as carrying heavy objects easier. While some debate exists about the superiority of hammer curls over traditional bicep curls, both exercises have their unique benefits and can be incorporated into a well-rounded arm workout routine.
In conclusion, hammer curls primarily work the biceps, targeting the long head of the biceps brachii, the brachialis, and the brachioradialis, while also helping to build forearm and grip strength.
