I don't know how it's in the US, but here in Russia professional ballerina can't be (even slightly) overly tall or overly muscular. Well, if she wants to ever be a prima, and not a part of corps de ballet during her professional carrier. Because every additional centimeter in height and additional muscles adds to her weight, and it's additional workload for her partner male ballet dancer. After all, male ballet dancers, while have strong arms, still need to be lean themselves: it's ballet aesthetics, and they need to graciously dance, so they can's afford to be akin to bodybuilders or sportsmen-heavylifters.
