Judo or Brasilian Jiu Jitsu. Any grappling I guess where part of training is deliberate practice and part is kind of competition/sparring.

Any reason why grappling trainings are relaxing?

When you are thrown or being choked you are unable to focus on anything else than the moment itself. Its extremely liberating and picking both of those activities were detromental for my health

Flow. You can't overthink grappling, or you'll sabotage yourself. You have to let your mind flow like a river.

Never tried it. Very interesting.

Flow is quite addicting.

I agree with the others that Flow is part of why grappling is relaxing.

But, the another reason is that it's an amazing stress reliever. After a good grappling session, you will feel incredibly relaxed and calm.
