I seem to be getting into the habit of doing the workouts twice, but in the spirit of intervals, I think this is a good thing. Also, my time spent "in the zone" is relatively low on a per workout basis.. probably because I work cardio so much.
I'm sure the twice a day thing will stop next week when my calf has healed enough to go back to jiu jitsu. P90x, BJJ and ONE insanity session ought to be enough, even for me.
