Later this month I will be competing level 8. My tumbling pass is a roundoff back handspring back tuck. My back handspring and back tuck are pretty much perfect, however my roundoff is causing me problems. Everything is fine from a step or power hurdle, but when I run into it it's not only crooked but I also land my roundoff with my legs apart. Any tips for getting my legs together in a roundoff and keeping them straight?
