I'm a traditional Gi guy, but I clearly see the difference between Gi Jiu Jitsu, and NoGi MMA Jiu Jitsu, which is why I want to learn all the clinching guards, especially RG, as I want to compete in MMA one day. However, I am not able to get into a full butterfly or lotus stretch yet, and I don't want to just start pulling my legs up before I'm flexible enough and hurt my knees.
I've been doing the butterfly stretch probably about 5 times a week since the start of the year, for about 4-5 minutes each time. I'm getting close, but it's taking a while, and I've heard that the last few inches of the butterfly stretch take the longest. Is this routine (4-5 minutes of butterfly stretch, 5x a week) enough stretching to get to Rubber Guard level flexibility within a reasonable time (1-2 more months)? What I want to know is if this is enough stretching, or should I be doing more? Different stretches? Also, how long did it take you guys to gain the flexibility, and what was your stretching routine? Thanks!
