If you want to advance to more challenging exercises

I used to be a big fan of working out at home until I realized that these exercises you see on DVDs and videos tend to cater to beginners who don't want any real challenges. Sure, it's important to take baby steps with your weight loss needs, but what happens when you feel you want a bigger challenge? You have to turn elsewhere.

Slim n 6 is a set of DVDs based on cardiovascular workouts you can do in the comfort of your living room. You don't have to use any weights or any other equipment, according to advertisements. However, while the company guarantees results in as little as six weeks, I'm worried about where you're expected to go after that period is over.
