why would you ever wish yourself shorter ?
One of the reasons of lifting is to be bigger, so why would you want to be smaller
trust me, some of my best lifting buddies were 5'7, 5'10 whatever, and they would KILL to be 6'1 or 6'2
i'm 6'2 but would rather be 6'4
its not harder for you to make visible gains, it just takes longer
but time we have, and a finished product at 6 foot something is better than one at 5 foot something in my opinion
