She'll turn 17 on January 3rd. Usually though, weight is gained after puberty, usually around age 16-18. Kimmie and Caroline were both around 17 when their builds changed a lot, going from really thin to sturdier and muscular, even though at that point they were probably past puberty. Mirai Nagasu also looks to have filled out some since last season, though in her case it hasn't seemed to affect her jumps negatively.I really enjoyed her skating. I love her body line and her wonderful flexibility in her back. I havent enjoyed too many ladies thus far, so this is a real treat and a surprize. As far as puberty, how old is she? many girls start by 13 unless they train like dogs or gymnasts. I wonder what her parents look like. Thats always a good prediction of what is to come.
