Sit with your back flat against a wall in a straddle, then have someone to sit in front of you and push your legs back until you get even better at it. When you feel more comfortable with that, start trying splits without the wall , and remember practice makes perfect!!:)
Sit down, move your legs apart, and face a wall. Slowly scoot your body toward the wall until your inner thighs begin to touch it or until you feel too much pain. If there is pain, hold it there and wait until the pain subsides. If there is none, you have a middle split! If you're doing it correctly you will be doing a middle split with your legs on either side of you and you should be facing the wall.
