Stadion's Sports and Martial Arts Training Discussion

I have done test. I don't get 90 degree (when looked above) I get like 85. I feel stop but I think its not because of my bones. It just doesn't feel so

When i try to gete toes up split there's stabbing pain in my hips. Is it because
they are too tight or is this because of the shape of my hips? Butterfly stretches should help? I just get 45 degree angle, not 90.
