It’s no secret that when people contradict themselves, it has the effect of making the flaws in their actions or statements seem glaringly obvious. But what about when WE ourselves get caught contradicting ourselves by someone else?
Yeah it does matter. Chin-ups and pull-ups work different muscles. Pull-ups are also about twice as hard. If you are going to say the grip doesn't matter than everyone would be doing chin-ups because they could lift much more that way.
No, it doesn't. If your goal is to build a bigger, stronger back, it isn't going to matter.
