im 6ft 1 and growing. fairly thin about 145 pounds (working on it). Anyway my wrists are insanely skinny. So are my calfs to an extent. My friends 5'9 and 185 pounds very well built we're both 17 but he looks like he is in his mid 20's anyway his wrists are about twice as big as mine. Im 6'1 and i can easily loop my thumb and touch my index finger there is even space there. Do your wrists widen during puberty or anything is there a chance they would get bigger or am i gonna be stuck having tiny joints forever. My calf was about the size of this guys forearm .
