I switch between two mesocycles where I train 3 days a week, PPL DC training, and 4 days a week, full body Fortitude training (It is MTThF where you focus on upper body one day and lower body the next day with a couple pump sets for the non-focused parts.) I actually get a little more recovery from the 4 days a week, because when I do to DC training my intensity is 100% every session.
I do something similar. Muay Thai 2x week, BJJ 1x a week and then my whole body split in two days. I have been doing this for a while now and feel WAY better and not so run down as when I was doing the martial arts and a 4 day weight split. BJJ and weights after was a bitch.
