Does anyone know some really good lower body stretches? im pretty flexible, so i need something advanced. thank you!

Well if you want to work on splits. The key words are "gentle" and "often". Clear floor in front of a wall. Lay flat on your stomach with your legs spead as wide as comfortable and your heels touching the wall. Lay your head on your hands. The key to getting your lower body to relax is leaving your head resting on your hands at all times. Now gently back up into the wall until you feel a little pressure from the stretch. Take a deep breath and slowly let it out until you feel the muscles relax. Your pelvis should be resting on the floor. Repeat this several times a day every day. Six months of this routine, allowed me to drop into a full split with no warm up! I am a man and was never able to do this before.
