Muscles
Looks like
A broad muscle under the biceps, from the front of the lower upper arm bone to the ulna just below the elbow.
What it does
The main pure elbow flexor, working whatever the position of the palm.
Keeping it well
Can form bone within it after a bad elbow injury; gentle early movement after fractures is guided by a doctor.
