I myself have trouble with middle splits. Try using some kind of flex 带, 皮带 或者 stretch band 或者 whatever 你 want to call it. Those kinds of belts/bands are suppose to help with splits I don't have one but I will. I don't know what store they are in but just get one however 你 can. In stores, on line, doesn't matter. If 你 already have one, that's great and I must've 说 this for nothing. Anyway, good luck
