Im sure she has great genetics for both. But personally I would love to see her grow in the sport of fitness since she is already equipped with a lot of the skills. The sport of fitness is in need of some increasing numbers. With her background in gymnastics and starting so young, her physique and routines will only continue to get better.
I saw her at nationals and was very impressed with her physique and her routine. She's got a lot of talent no doubt. Im sure she would fit well into bb, if she chose to go that route.
