That's a muscle I'd never heard of before. I had to look it up.

Interestingly, it's a muscle that is very tight on my left side.(Nonsurgical side) However, it has loosened up a lot with the joint mobility exercises.

The nice thing about joint mobility is I've learned to just concentrate on trying to get full range of motion from each joint, and combination of joints. I don't worry about this muscle, or that muscle, and since I'm using movement, the muscles seem to strengthen themselves as they release and get healthier. Scott Sonnon has taught me to think of the body as one big muscle that works together, rather than a lot of separate parts.
