And it's one of those exercises that the load can exceed its capacity pretty quickly. So that like, maybe it's only capable of handling 30 pounds and then when you're doing a chin up and it goes and it drifts so far that it's now you say you're a 200 pound guy you've got let's say 100 pounds through one arm and 100 pounds, this is simplified math that obviously is offset by other muscles, but 100 pounds to one arm 100 pounds to the arm, 100 pounds off of a muscle that can handle 30 is not going to take many repetitions to strain it and you're going to feel that maybe by the time that a set's over or certainly by the time that workout's over or the next day you wake up and you've got that notable stabbing pain.
