Really depends. In 8th grade I was 106lbs and about 5 5 (lol) and I have really long limbs for my height. I wrestled a lot of kids who were 5 3 and under. Since I run track and that's the only thing I do now, I was much faster than my opponents so I could grab them from a far reach and outspeed them

Yea They are quick and probaly get the big guys down by going underneath them nicely

No.

I have a better sport for the small or thin.
