Hiya Mike..Good to see all is well with yourself still mate...
I would agree with what Mike said about listening to what your own body says about overtraining..What other people do means nothing except as a very general guide..I would say that leaving a days space between training would be good idea though, and as Mike said, more rest needed when training involves damage to your body (Punching, bruising etc)..
I train currently 5 times per week, three at the Dojo and two/three at the gym, and leave a day between them more or less, except on the weekends..It works me well enough..Saturday training is all day and I usually wake up feeling half dead on Sunday, but since I have the time I like to train then too..It works okay for me, but (basically) any schedule that your body can get used to will be okay in time, if it doesn't you'll know it.
Regards.
