If you're new to CrossFit, working out, or even gyms in general I recommend Mastodon. When I joined I was completely new to CrossFit. Zak, one of the owners and trainers of the facility, greeted me with open arms. He made me feel really comfortable in his gym and with the equipment. I think for anyone, no matter the fitness or experience level, going to a new gym is intimidating. What stood out the most to me at Mastodon was all the members were really friendly. They new each other by first name and would chat with you before/after class. It's not just a gym its a place where you can make friends and connections with people that have likeminded goals.
