I'm able to do a few single slow muscle-ups with short breaks in between. But what I find very difficult is doing the negative when going down in the same slow tempo. It seems to me that a negative muscle-up is harder than the actual muscle-up. This confuses me because I often read things like "when you are not yet capabale of doing a muscle-up, do train the negative first". Especially in relation to the bar muscle-up (which I cannot do yet) I often hear that advice.
What do you think, is the negative really harder or is it probably just a personal issue due to some wrong technic?
