I LOVE 4DS!! It was my 4-5 Cathe DVD (I guess I should say "DVDs") and it is still one of my all time favorites. I have to admit I adore the step routines. They are a little easier than some of Cathe's other step w/os, but they are just so much fun I find myself reaching for them again and again (I actually just did the HIS/LIS premix yesterday). Now, it did take me 1-2 times to pick up the steps and I tend to catch on to step routines quickly. But it is absolutely worth the time to learn the routines. The Bootcamp and Kickbox cardios rock as well! I find the bootcamp cardio challenging and i'm often gasping for breath by the end. The kickbox cardio is also one of my all time favorite kickbox routines. There is something about the punching combo at the end that make me feel empowered and strong. Did I mention 4DS is one of my favorites??

I really like the variety the cardio portions offer - yes LIS is easier and bootcamp is harder but the variety is what keeps the w/os interesting and fresh.
Now, onto the weight sections. I'm still a weakling when it comes to lifting, so i'm only lifting about 50-60% of what Cathe is lifting BUT that's okay. I consider it a challenge and i'm already progressing. When I first got the DVD a few months ago, I was using 10 pounds for the one arm rows (I think Cathe is using 30 or 35 pounds) - i'm now up to 15 pounds and honestly i'm ready to move up to 20 pounds (I just need to buy the dumbbells - LOL). I like the slower pace so I can lifter heavier than I normally do and really push myself; I always feel fantastic - and tired - by the time I get to the end. Plus each w/o is just fun and I don't have the "dread factor" like I do with other workouts.
Okay, i'm done gushing now. Haha!
