Join a gym or make a weight room in your house. I would recommend the gym more, especially one where you know other fighters train. You get to meet people, share expierences(if you are into talking while working, i am not.), you learn from others (beit their misstakes or qualities in techinque, work ethic, etc.), also it sets up a the instinct of your body and mind knowing its tie to work hard when you are in the gym or even your own workout room. Don't go for gimics and flash just do whats been proven to work and add your own flare to keep yourself motivated and inspired to keep improving. Save your money on these things, "go anywhere" workout products just aren't effective, maybe you see results and improve but I feel in the long run they will fail you or improve you less than hard work in the gym.
