Different kind of muscle?

[YouKnowWho]

I'm proud to present my daughter's excellent performance. Do you think CMA training can help you to achieve this kind of flexibility, balance, strength, endurence, body alignment, and inner connection?

Onething in my mind is that I knew she has never done any weight training in her life time. To be able to hold on the pole with 2 arms and keep her body upside down (almost like a human flag) does require some arm strength. My question is, "Do you think her arm strength is different from those who builds big muscle from weight lifting?" What's the difference between these 2 kind of muscle? I know I'm stronger than her but I can't do what she did, why? Did she take "short cut" for her strength development? What might be that "short cut"? All my life I was working on big muscle, it seems to me that you don't need to have big muscle to do certain thing (such as "human flag").

What' your opinion on this?
