You guys really consider those wrestlers to have "T-Rex" arms? I actually spent the last 7 or 8 years thinking my arms were too long for my height cuz they go to literally the halfway point on my thighs. My armspan is exactly my height by the way, 158 cm.
I think that we, the people who consider or undergo LL, tend to overthink about proportions. I guess the normal population will not see the shorter armspan, unless if someone goes and does extreme amount of lengthening and creates very obvious disproportion.
With the above wrestlers, I did not realise Rhinos shorter armspan but I only realised Eric Youngs armspan after I became aware of LL and proportions.
At 158cm, I guess extra 10 cm will not create obvious disproportion if you do decide to lengthen both tibias and femurs.
