I lost 20 lbs. 5 years ago with Slim in 6 before I got pg with my dd. It isn't a gimmick, it is a great work out! It did it all. Good cardio, strength, and toning. I haven't gotten myself back into the groove yet to do it again, but I want to because I know it worked. I liked Slim in 6 because it had everything in it and I didn't have to do seperate workouts for cardio and toning and I did it without leaving my house. The way I did it was watch my calories, choose better/healthier food, and do the videos/dvds 6 days a week. The plan isn't this wacky, hard to follow eating plan. It's just normal foods, but they encourage to make better food choices. I plan on doing it again, but not go at it so intense like before. I followed the program to a T and I lost 20 lbs. in 6 weeks and was toned. I was intense. This time, I'll not be so intense and just do it because I need to do better for myself and not worry about a time frame. I felt great after the work out! Yes, I was very sore for a few days once I started, but after the first 2-3 weeks, you can tell your body is stronger and more toned. I could climb up my stairs easier and I didn't even know it was diffcult before. I could just tell my body was healthier. So, that's what worked for me and now I've got to do it again.
