This one is for the veterans:

We have all seen the bodybuilding shows where each the competitors are nothing but a stage full of jumbled mass, and very few of them have any type of real symetry to speak of.

Do(can) exercises such as pilates or yoga give that polished finished look,
similiar to Frank Zane or Bob Paris in their heyday. Think about gymnasts and ballet (dance professional). Their bodyfat is low, and you can see a musculature that if developed to competition levels would wipe out the average bodybuilder.

Is this level of developement what might be termed muscle maturity?
