I've been struggling to get the front splits right and stretching for it. I know the key points for having the front splits in the correct form; Hips are squared, front leg forward and locked out, rear leg behind and straight, and upper body upright. What I don't know is how do I keep my rear leg straight?
Pointing the toes to the side is the best bet, but still not straight. If I try to get it straight, I'll engage too many muscles and could ruin the stretch. Pointing the knee and toes of the rear leg directly at the floor is the least helpful in my experience as it doesn't really do much. Cheers.
