Adding to the develope discussion, I like to practice mine with an ankle weight on-- it's really hard, especially at first, but I feel like I make faster progress that way. In regards to splits, some things I did when I was first getting my splits in high school: 1) Make sure you stretch daily, and go into your splits daily. Splits need to be held for at least 30 seconds in order to give your muscles time to relax into the stretch. 2) During your daily stretch you can try to do oversplits instead of regular splits (even if you don't have your regular split this will help you get it faster, and if you have your regular split it will continue to increase your flexibility). For those unfamiliar with oversplits, you want to get something that you can put one or both legs up on top of while doing your split--when I was doing oversplits regularly I used a stack of books and then I could add a book when I needed to increase the height. It's going to be uncomfortable because the idea is that you want to stretch in such a way that you can get your hips below your leg line, but the angle seems to help people to get their splits faster. 3) Try to keep your shoulders over your hips when you're in your split-- this isn't easy if you don't have your split yet, so get set yourself up between two piles of books (noticing a trend here?) or yoga blocks or stools or whatever you have so that you can put your hands on something other than the floor to try to keep yourself aligned. If I think of anything else I'll come add it.
