Each muscle firing is it's own step. Something simple like kicking a ball is one action with multiple muscles firing it that action. You need at least 5 muscles involved in your action Example: Description: Picking up a glass of water. Muscles: Biceps, brachialis. Step 1: The brachialis has an origin at the humerus and inserts at the ulna. Contracting is a flexion action. Example: The [Muscle] has an origin at the [Bone] and inserts at the [Bone].
