Saw a guy at a mates gym hanging from the pullup bar not moving for ages, I couldn't figure out what he was doing and figured he was just stretching out his back. Well I was kinda right...I over heard him and his mate talking about how stretching like this will lengthen the lats to get a bigger back..
I had to turn away and try and contain myself.. Go the bro's!
Sounds like strong bro science lol
