I'm only a few weeks into the P90 exercise routine, but already, I'm seeing results. While I haven't lost any weight per se, I'm definitely more toned than I was when I started. And, I'm only 25 days in, so I have to think things will only improve from here.
I really like the weight training days--I will definitely base future workouts on it. I absolutely loathe the aerobic days--I will definitely trade those in for the treadmill after I complete the 90 days.
I'm happy to have found an exercise routine that works and that I don't mind doing (well, not too much, anyway).
