I've read numerous times that medium grip pull ups/ chin ups are the way to go as they allow for a greater range of motion so therefore in theory better lat development.
However I read recently that wide grip pull ups/ chin ups work the outer lats more in fact it states the wider the grip the more outer development, which would then mean greater width.
So is it true the wider the grip the more outer lat development ??
Please don't reply with you should use various grips as that I already know i'm just interested on if the wide grip effects the outer lats more or not ?
Thanks in advance for any replies
