ex something an antagonist muscle might do
bend elbow
if the antagonist bends the elbow then the synergist___?
straightens the elbow
if hand palm is up
biceps does most of work of flexing therefore is prime mover
if thumb is up

brachioradialis is prime mover
if hand palm is down
brachialis is prime mover
why is a chin up with palms facing forward is easier than if they were facing out
because biceps are usually larger and stronger than brachialis
