Well I'm going to go to a free trial at a nearby gym. I can't decided whether I want brazilian jui jitsu or mma, but I'll decide that later. Anyways I'm a girl, so like what should I expect first day? The only think they told me to bring is shorts or sweatpants, tshirt, and water. Anything else I should know or any tips? I also don't have much background with any contact sports. I've done a little bit of kickboxing and some wrestling (wwe style), I'm also 17.
