Now I know this is a very open ended question with a lot of variables but I was hoping to maybe gain some insight. I train in some MT and BJJ by the way and have no plans of competing ever. I just enjoy the sport and do it for self defense. I have never been in a fight outside of class though. Right now, I am 5'9 and about 155 lbs which is too light in my opinion. I don't feel like I have the size and strength to be effective against a larger opponent. I know that it is fully possible for someone my height to completely destroy a guy who is say over 6 feet and larger. I just don't feel like I have the strength to do so. Is my weight good or should I try to pack on 10 - 15 pounds?
