Just got into Jiu Jitsu and Muay Thai last fall. I've been enjoying them a lot, and I have never had a cardio workout like going 3 5 minute rounds with someone experienced in Jits. I usually wind up laying on the mat gasping for air at the end. The wife is doing it back home as well, so I imagine I'll be doing some amateur fights next year.
My Training Log
Personal tips that I've learned along my still short journey:
Leave your ego at the door.
Prepare. Showing up dehydrated, hungry, and tired will guarantee failure.
Be ready to fight for that grinder of a PR.
Listen and learn. Absorb everything you can, and assimilate that knowledge.
