THE PROBLEM WITH STRAPS
HOW THE LATS WORK
There’s no such thing as working just your lats. As you can see from the picture on the left, the lats are part of the very complicated muscle system that makes up the back. During the course of your back workout, other muscles in the back and shoulders invariably become involved. Most good lat workouts make demands of the teres major, your rear delts, the long head of the triceps brachii, and a number of other stabilizing muscles. Your traps (trapezius major) are frequently called into play as well.
