Musclehead

Slang for someone whose life is dominated by training.

Many muscles attach at a single point on one end and at multiple points at the other, somewhat like a bunch of bananas, but better at lifting big, heavy iron with. "biceps" means two heads; "triceps," three; "quadriceps," four. often the multiple heads of a single muscle will attach to different bones on either side of a joint. The calf muscle has two heads, which connect at the bottom and attach to the heel: the , the top of which attaches above the knee joint, and the soleus which attaches below. Because of this, if the knee is bent (such as when performing seated calf extensions the gastrocnemius is put in a poor position to transfer force and the exercise is performed largely by the soleus head.
