A couple of months ago i added regular pullups to my routine and saw very good results with my lats as far as taking a v shape. I've never been happy with my lats until i added them so i have to attribute my new shape to them. So i'm thinking about adding reverse grip pullups to hopefully blast my biceps and take them to the next level. Is this a good exercise to expect gains? If so, how wide should my grip be? Any other advise?
