What are good stretches for your middle splits?

OMG same!! im terrible at box splits :/
what i do at college to strech is streching my legs across a bacheca and just sit there, and every minuto o 2 it relaxes the musles meaning that your legs can stretch più :) but be careful doing this!! cause whenever i do it it pulls on my knees, so te have to keep your feet flexed upwards and knees facing upwards, otherwise te can damage te knees badly...hope this helped :)

Uh, Put Your Left Leg First On A Chair o Something To Put Your Leg On, And Put Your Head Below It... Then, Go Againest A bacheca With Your Foot Touching It, Then Lift Your Leg All The Way Up On The Wall... Lean Up Againest A Fridge And Lie Down On Your Back And Try To Stretch It As Far As te Can Till It Hurts, Lean Againest Your Fridge Again And Push Closer And Closer Till Your In Your Middle. Thats All I Have
