i have loose ligaments and stuff. basically if you can bend your fingers 90 degrees backwards. but i have this through out my whole body. if you find yourself while training doing a kimura way past the point of breakage. then just think that person has loose ligaments and stuff and go further. I have always wondered why i could slip out of so many things. If you know you have this, try to use it to your advantage. if you find yourself doing an ankle lock twice as far and the opponent with a careless expression just starts to grab your leg. he has it. it is quite funny if you have it. I want to know if anyone else has this? i don't have it as bad as some others do, but if you let your arms dangle and it doesn't hurt, but you feel like it popped out of socket you have it. or atleast have it in your shoulder.
