wow thats a terrible idea. stretching to actually lengthen the muscle is awful, you have plenty of length in ur muscle to simply drop into a split, the problem is your nervous system wont let you because it knows you dont have any strenght in that position. i recommend you research "isometric stretching" and read "relax into stretch" by pavel. iso stretching is 257% more effective than regular stretching and ur not tearing anything.

this post may be old and im never gonna come back to this board, but if u want splits go with iso stretching, its safer, builds strenght and is WAY! faster...and u really need to warm up to get to max range, ur muscle instinctively are at that level all the time.
