I'm willing to bet a huge percentage of you out there who're like I've never had a sore lat, you know, I've done a lot of pull ups and things like that, if you do that eccentric only you'll probably wake up the next day going, oh gosh, I feel it there. And that's a sign, even if you didn't feel it in the workout, but it got a little sore the next day, keep down that path.
