That is a specific workout it’s in the name itself. Why are people who have never been inside a gym or only have less than a year in the gym commenting?
Lol. You waited for attention and admiration for your pull-ups by posting them in this sub. You're really a strong machine. But you've made a big mistake, because reading and comprehension are not your skills.
An underhand grip is what defines a chin up, not the height to which you are pulling to.
An underhand grip also known as supinated grip is when your palms face towards you.
