I'm 5'6, but my torso is actually pretty short, so when I sit down I don't look very tall (I'm all leg xD)
I wish I was shorter, though :/ I hear my coaches talking to the little kids, saying 'gymnasts are short, that's why you're little etc. etc.' and I want to go smash something.
Plus it makes learning kips really annoying because it's hard to get the right swing, and one of my coaches is very lazy and never wants to spot anyone over, say, 5'2.
