So, I know how some kids are just naturally super flexible, but not in this family. How big of an issue is that for a 4 yo just starting gymnastics? Sitting down she can straddle maybe 100 degrees, and with her legs straight in front of her she can just touch her ankle bones. I know she gets it from me, I can't even straddle more than 90 degrees and even that hurts after a while. I'm trying to work with her on it, but I'm afraid to push her too hard. Is this something she will be able to work through, or do gymnasts just have to be naturally flexible??
