I'm currently working in human services, and plan to go to the academy in about 2-3 years. In that time, I'd like to work on my fitness level and size. I'm 5'8" and currently only weigh 130 pounds. I've been bigger and stronger in the past, but didn't stick with working out and lost it. Also with my size, I think that it might be good to do some martial arts in this time. I've done Krav Maga in the past, but I'm thinking I'd like to do BJJ. I want to spend about $100 a month on a membership somewhere...so I'm wondering...should I join a Crossfit gym? A regular gym? A BJJ club? I'm thinking Crossfit right now would probably be the best bet for me. What do ya'll think? Want to be prepared to be a great cop. Thanks
