Yes! MMA is a great form of training. If this was your first training, you'll feel muscle-aching tomorrow and the day after :)
But seriously, MMA is one of the best training forms in my opinion. You get great training, streching, and last, but not least, the ability to defend yourself if you should need it (let's hope not).
Back in the days, I used to train kickboxing, and then a few years with MMA. But now it's just running...and i miss MMA training!
Maybe I have to become a YES-man too? :)
Ohh, that sounds like something I want to become good at, especially the defending myself -part :) Here I think the biggest threat is moose, so will need to figure out how to stop a moose-attack ;)
Sounds like you definitely should become a yes-man! ... and get that helmet too when you're at it ;)
