Ok. I'm 16, been doing BJJ for a little bit over 2 years and a blue belt. The thing I have the most trouble with when we spar, is staying out of leg locks. I'm always getting caught in those by another blue belt. And its always the same guy thats doing it. I give him all the credit for going for them though, he always gets me in them. I'm wondering how to stay out of them and how to position myself so that I dont give up my legs for any locks. Answers and opinions would be appreciated. Thanks guys.
