Back Exercise Guides - Photos and Instructions For Big Lats
Your
back is characterized by three smaller muscles: latissimus dorsi,
rhomboids (upper/middle back), and erector spinae (lower back).
These three muscles, along with smaller supporting muscles deep
beneath the skin's surface, play a huge role in almost everything
you do, from swinging a golf club to sitting at the dinner table.
Latisimus Dorsi: Run along the sides of your back and are most
commonly called lats. Your lats help you extend, rotate, and pull
your arms to your body (adduction), important in pulling activities
such as rock climbing and rowing.
