#flexablity

Stretching everyday. Easy and gentle at first and slowly progressing into deeper ones so not to pull something and hurt yourself.  What I mean is you stretch as far as you can now (so there's a nice stretch going on the muscle but nothing painful! if it hurts, do not do it, bring your legs in a little) and slowly start to work your way to pushing a little further

For splits (this is how i learned to do it) front side lunges like this: 

Again only going as far as you can, never more.

You could also do Reverse lunges, again slowly progressing:

Another great stretch, besides a single leg lift (this you just lie on your back and raise a leg into the air, pulling slightly back while keeping the other leg firmly planted)  is a straddle which looks like this:

Again for this you basically want to spread your legs as far as they'll go out, keeping your feet pointed out. You can lean over them on either side and down the middle to achive a nice stretch.
