its definitely possible. how long it takes and how easy it is for you will depend on your natural flexibility and how much time/effort you put into it. i was seriously the least flexible girl at my studio a year ago. my "split" was a high lunge, lol. a year of solid dedication, and now i have a beautiful oversplit on my good side, and a decent (if uncomfortable) floor split on my bad side. if i can do it anyone can! (i just started working on my middles, my goal is to have those by next year). i used the lessons on here and aletheas splits DVD as a starting point. they're both great. the most important factor in gaining flexibility (imho) is consistent training, and thinking long term. dont get frustrated and give up! good luck!
