I have been trying to learn Jiu jitsu from the past one year. I live in India so there's no formal Jiu jitsu school out here. I know a few guards and submissions. I have observed that since the last few weeks my game has dropped, the people I used to control or submit earlier now are often able to pass my guard, this is frustrating me.
Ps: I have this obsession to learn to play from the guard and aim for technique and not power, a few of my rolling partners are muscled up and often throw me around. I myself am a 190 lb 6 ft 2 inch person but I have strength next to zero. Can anyone please help me out with what to do. Should I roll more or drill more.
