I know...Brazilian Jui Jitsu , I never did it, but know it, my friend do this..
and really interesting So keep training if you can.It is important to do also something else than only programming.
I gives 3 or 4 hours per week for training, and it's enough.
I had to stop training,half a year ago, because of work (I'm full time
programmer) but I start again with training
