Luckily tha good Lord blessed me to be able to kick high and I'm very limber.I think I was born with both naturally,I do work at them,but can tell you from personal experience that it's not tha thing to be worried about.Just go out there and give it all 100 percent of ya.At tha end of tha day even if ya can't do a split you'll know you gave it all your effort,and it sounds cliche but that is truly whats more important.
