In my quest to find the "right" place to train, I came across aforementioned gym and stopped by there earlier this evening to check the place out, see what kind of vibe I got from it. I walked into the room and was greeted by the sight of god knows how many huge, sweaty guys, grunting and rolling around on the mats all red in the face. My first internal response was: RUN!! There's no way they'll take you seriously; you're just going to look stupid! They'll laugh you out of this fucking place! How could you ever think you'd fit in here??
Luckily, before I turned and walked right back out, the owner and head instructor came over and introduced himself, talked with me for a while and convinced me to return tomorrow night for a free trial during the Fundamentals class. He said if I show up an hour early, I can join in the kickboxing class too, which is great since that's what I primarily expect to be doing. So I'll be coming back tomorrow evening and we'll see how it goes then, and whether or not I feel like this is the right place for me. At this point, seeing BJJ up close and personal (I'm telling you, it didn't seem half as intense on video), I'm thinking I'll try it once and then probably stick to kickboxing.
