Definitely agree with Stacy and JPG. Diet is 80% of your results. With that said, when I'm eating clean I see different results with any exercise program. However, my leanest results come with Cathe's metabolic resistance training a few days a week, one or two hiit workouts and a 4-5 mile run once or twice a week. So I'm working out 5-6 days a week, depending on the week. Low Impact Series also created lean results for me. Also, I always get great results with P90X. I try to do it once or twice a year.
