What action does the biceps do?
a) Curl the arm
OR
b) supinate / rotate the hand
TEST
Before answering, place your arm in the fully curled position but palm facing down or over hand as in forearm pose or overhand grip.
Hold your bicep with your other hand and feel it as you curl. Curl as hard as you like into a fully bent overhand grip curl.
Does your biceps flex at all?
With your other hand now squeeze the biceps as you rotate the hand to a fully supinated, fully twisted palms up position. ( or beyond )
Keeping your arm fully bent the whole time.
Muscle peak is determined by genetics but you need to know what the biceps actually do to hit them best.
Just try my test. You may be surprised.
