Ha thanks man, I do a lot of negative repetition as well. Those neg reps will expand those large twitch muscle fibers to the max. I read a few research articles about how negative repetition is one of the best ways to get stronger. I don't do much negative bench though because I always go to the gym by myself and you need someone you can trust / that is strong that can spot a negative bench session lol.That's insane. I'm pretty strong for my size i guess but I'd be lucky to top 8-10 pull ups and 12-15 chin ups consecutively, youre a beast lol
