Max Weinberg hits like that as well (and he's had umpteen surgeries on his hands)I noticed that he and Ringo hit the snare like this. Almost laying into the drum. Alex Van Halen does this too. I hit a lot of rim shots but my hand always come up from the snare. I think I would get shock in my arm hitting the drum like that. Obviously this technique works fine for all of them. Very cool video!
