Name of the muscle under your arm pit?

[MonarchX]

Its the muscle on the side of your rib cage, right below your arm pit.

Is it part of your lats?


When I do chin ups with hands facing me, that muscle is heavily worked.

Yet, when I do normal pull ups, that muscle isn't worked that much.

lats, chinups and pullups (palms facing away) really work that area, do what works best for you.

OK, just making sure its lats.

They look like fingers and freak me out, like some alien form hugging me.

chip ups is my favourate, you can feel obviously the work of that muscle.

here are some exercises here:

you are probably feeling it worked during chinups because you allow your scapula to retract and protact during the movement more than you allow during pullups.

Pullovers are proably the best exercise to work the serratus.

Also search serratus crunches

Why ask when you've answered your own question already?
