This one suggests that a supinated grip during the biceps curl may be superior in eliciting the greatest excitation for both biceps brachii and brachioradialis during the concentric phase of the lift.

- This study analyzed the level of excitation of the biceps brachii and brachioradialis during the ascending and descending phase of the biceps curl performed with three different handgrips (supinated, pronated, and neutral).

- Both biceps brachii and brachioradialis exhibited greater levels of excitation with the supinated compared to the pronated and neutral handgrip.

- The lowest biceps brachii excitation was found with the forearm pronated, while the excitation of brachioradialis was similar in the neutral and pronated condition.

- Interestingly, the anterior deltoid exhibited greater excitation with a pronated and neutral than the supinated handgrip.

- These differences appeared only during the ascending phase.
