When I switched to 2 days of cardio (1 step, 1 not) then a day of full body weights (started w/ MM then rotated thru to PP and SS)Repeat 1x then a yoga or rest day to make a full week. I noticed a huge change. It kicked my butt right off the plateau I was on and I started losing again. I still have some weight to go and am on a temporary medical set back but that's the plan I'll be getting back on, although I still want 4DS. I didn't notice any changes right away, but after about 2 weeks my pants were looser and at about 4 weeks they were falling down, as were the numbers on the scale. I lost about 5 lbs the 1st month (not bad) of working that program, but it looked more like 10. Lost about 20 overall over 3 months of that. Plus, I gained strength and endurance. I just said "today you are going to lift heavier" and I did. No ifs,ands, or buts. I really had to watch what I was eating, as well. But it seemed to kick start my metabolism and weight loss again. The only thing I noticed is that I get hungrier more often. I have to eat every 3 or 4 hours, but as long as I watch what I'm eating, no problems. I switch the weight workout every month. Seeing as it worked thru the holidays, I will call it a success. I am now just trying to maintain til I can get back at it. So yes, it can and does work, but every body is different, so you need to figure out whats best for you. I think a lot of it is trial and error. I also think you need to give any new program a chance to work. I say give it 2 weeks to a month see if it works for you. If not, then try something else. You'll eventually find your "magic formula" By changing up the cardio routines daily and the weight routines monthly, you'll keep your body from getting bored and stuck in a rut. I can now match or exceed Cathe on everything except quantity on pushups and tricep dips. When I am feeling better and healed, I will purchase 4DS and climb that mountain.
