"DB Curl Twist" typically refers to a biceps exercise using dumbbells that incorporates a twisting motion during the curling movement. This variation emphasizes both the biceps and forearms.
"Reverse DB Curl" refers to another biceps exercise where the palms face down during the curling motion. This targets the brachioradialis and brachialis muscles in addition to the biceps.
Together, these exercises can provide a comprehensive workout for the biceps and forearm muscles, enhancing strength and definition in the upper arms and wrists.
