Personally, when I was lifting heavier weights, each bodypart go worked hard once a week with the Gym Styles or the S&H series. Then the cardio was in the AM...30-45 minutes of whatever I felt like. One of the weekend days was a workout like DM or Cardio Fusion and abs, the other day was a rest day. If you want to work a bodypart more than once a week, I would do a three or four day split, like the new workouts.
Results? I had always worked out this way, for years and years, I have pretty good muscle hardness and maturity, but can get too bulky looking, especially if my diet gets crappy, so since my surgery, I am trying a new approach to working out.
Pilates, yoga, the Squeeze, B&G-no weights, and circuit type training done outside along with walking. I am smaller than I was three months ago and am liking my results with this particular style of training. :7
