It's a great sport for getting fit.
I used to do MT and BJJ, they make a great combination. For now (at the beginning) you should use at least 4 to 6 more months concentrating mostly on cardio and long repetitions. Also you should dedicate 1 day for stretching only. 2 hour session of stretching burns calories like hell and it will make you sweat like a pig.
If you really enjoy the sport and want to progress as much as to get fit the basics will get you there; just keep hitting the bag. Do like intensive punching/kicking for a minute at a time (a minute is a really long time so don't start with full 100%) and 4 series of each with a minute or 30sec break in between
