wut u should do, wut i do, is lay on yur bak, on a pillow, or bed, and kick ur legs up and down for 3 minutes really fast. IT WORKS MAJOR!also, try moving your legs all around, and stretching them, well, yeah, kinda like the splits, but if u cant do them ( like me) i cant do them, just get as close as possible. GOOD LUCK!
