Why your forearm muscle works harder when you lift with a hammer grip
The function of brachioradialis.

This study looked at how a muscle in the forearm (brachioradialis) acts when you bend your elbow or twist your hand.
No biological mechanisms were identified in this study. This may be an epidemiological, observational, or survey-based study that reports associations rather than proposing causal biological pathways.

The brachioradialis is preferentially activated during elbow flexion when the forearm is in a neutral (hammer) grip position compared to supinated (palms-up) grip.
When you bend your elbow by lifting something, the brachioradialis muscle works much harder pushing up than it does lowering the weight slowly.
When you turn your palm down against resistance, the brachioradialis muscle fires more than when you turn your palm up.
No matter how you turn your hand while bending your elbow, the brachioradialis muscle works about the same amount.
