pushups equals big lats?

[Papi93]

The pushup works the pecs, front deltoids, and the triceps. The abdominals stabilize the torso during performance of the pushup. I use pushups and hindu pushups in my martial arts training. I use them to develop strength-endurance for punching.

actually pushups do work the lats, when you shoulders go slightly behind your back when your chest is to the floor, your lats help to initially flex the shoulders but then have little effect unless you really pull backwards with the lats to hit the floor faster than gravity!!
