DD's gym has decided that they must have all 3 of their splits prior to competing the next level. I realize everyone has different flexibility, but they want the girls to have these splits on the boards. I think this means 2 spring boards pushed together. Is this safe? My DD has 2 of the 3 I think, but is struggling a bit on one leg, meaning she has a couple centimeters to go. It just seems strange that this is a requirement all of a sudden when it wasn't in the past. Just wondering on opinions.....
