I want to do CrossFit but idk if it’s for me

I happen to go with a buddy to the 26.1 open last week. He invited me to go because there was a cookout after. The community there was great and they encouraged me to join but I’m a big boy.

I’m 6’0 and 350lbs and idk if I would make it out alive. I carry my weight pretty well so I don’t look very big but man there’s no way I can do any of the workouts. I’ve never even seen a CrossFit workout so I had no idea what to expect.

I’m afraid of getting hurt and are afraid of being judged for not keeping up.

For those that were on the heavy side how did it go? How has it been?
