That picture doesn't really do them justice, either. Jenny Lynn looked lean and trained - that's not a body produced by cardio alone. That's why I didn't really understand the callouts - I think Lena got hurt because she was thinner than the other girls - and she actually flexed during the quarter turns, so she looked leaner.
Of course, my tastes are much different than the judges, so I'm no good at figuring out what they want. For example, I think Stacey Simons (fitness) has an amazing physique, but she never makes the early callouts. I'm sure they think she's too muscular, but she's one of the few fitness girls with well developed hamstrings - and those shoulder caps are amazing!
