Awesome.
Try the buddy system, one on one, or a class to start with. Chris will make sure that you are working at the level that you can finish with, which is more than you think it is. You will be exhausted.
Not only am I getting way more fit, I am also learning how to box and defend myself, which is great. I feel stronger and more confident.
Everyone that I've met there has been really friendly. There are some kids training, women training, lots of men training. Pretty much all sorts of people. Don't be intimidated.
