I realized I never took any measurements when I started, so I don't have any quantatative data regarding results, but all my clothes are fitting better and I"m feeling awesome. I've lost probably about 5 pounds, and if you follow her meal plan you could probably lose several pounds a week. However, I like a glass of wine in the evening, and life is simply too short to pass my daughter's birthday cake or the opportunity to go out to dinner.
I've set up my workout space in our bedroom so I can workout early in the mornings if my husband is out of town or I can do it when the kids are watching their pre-bedtime tv show. I was using a yoga mat, but it wasn't withstanding my sneakers well, so I used the foam mat that I was about to get rid of. We used it previously in our playroom that has a wood floor when the baby was learning to walk (and falling a lot), but it was just getting in the way. It's easy to clean, withstands my shoes well with all the excercises and I can put it away easily if I need to. The only other things used in the workouts are the resistance band (comes with dvds) and the weights. I have 5lbs and 8lbs, but the 5lbs weights are getting a bit light for me. I may be purchasing some 10 pounders soon. So, it doesn't take much to get a great workout. I've been pleased so far!
