Why are my Zwift calves so undefined and my ankles so fat? I’m not asking for a perfect anatomical likeness (and you can leave out the varicose veins), but shouldn’t my avatar have a bit more definition after 100 Zwift hours and 3000km? I think the more Zwift km you ride, the more defined your avatar’s legs should get.
I agree! My avatar calves kill me!!
It’s not the size but the shape of the muscles that bothers me, quads just don’t look right from some views.
I’m guessing muscle contraction isn’t yet a thing so all you can do is show the non-contracted, aka undefined, legs spinning away.
Would be nice if the models themselves scaled to BMI as partly suggested, that way you can tell who are the climbers vs raw power riders 
My avatar has better form than I ever will, no matter how many miles I ride!
AKA Cankles (Where the calves and ankle are one)
A ‘Fat Lad At The Back Jersey’ would tell you all you need to know about my muscle definition!
