I've been training Judo for a while now. My concern is that half of the class is little kids and many of the adults are outta shape, overweight, or soccer mom types who are not into serious training. Only 4-5 people from the class randori. Judo is great, but I want to train serously. I have basically decided that this environment is not for me. I feel like a jackass when I look around & I'm training on a mat with 8 year olds. I want to switch to BJJ. My question is whether BJJ dojos are at all like this. I am looking for a training environment with other 20-40yr old males, not kids or soccer moms. What type of people does a typical BJJ class consist of?
