I do cardio training while im at work but wanted something more for training my body for better stamina and coordination.
I think most of us in the arts would agree that training on your own when you are a beginner is not a good idea in general. Reason being you will make mistakes and there is no one there to correct them. You could practice something wrong and learn it, only to have to unlearn it later.
But given your situation, what can you do? I'd ask if you had a certain art in mind and why? Because if we knew what your end goal was, we could direct you. For instance, if I knew that you wanted to learn striking I would tell you to find a heavy bag (or something that could work as one) and have you shoot a video of yourself doing basic punches and kicks (just the basics). In doing so we could give you some direction and feedback. The cardio involved in bag work can be awesome if done right, and by taping yourself you could get quick feedback and make corrections from the start.
If you are interested in more complex arts, then there really is no substitute for a live instructor. BJJ, Judo, Kenpo, ShudoKan Karate (the arts I have trained) really cannot be taught on your own. But Muay Thai/Boxing basics (which would help you in any art) can be to some degree and what I would recommend.
There are also drills you can do which would prepare you. Core work, balance drills and overall cardio training. What type of equipment do you have access too? We could look at your workouts and guide you on how to best take advantage of your situation until you are able to get to an actual school.
If you can come up with a heavy bag and a medicine ball, you can start training today! And if you can't we can figure something else out for you. If you are really serious, feel free to PM me as well. I'd be happy to discuss your situation in detail.
