S.B.
They're gimmicks. Save your money. unfortunately the only thing that literally works is exercise. I HATED exercising before my first daughter was born. I never did it. But when I couldn't lose that weight...especially the pooch...I resorted to trying. I forced myself to go to the gym and take classes. It was hell and hard at first...but I forced myself to go. After about, oh a month or so, the agony turned into feeling better and having more energy. Then I started to actually enjoy exercising. Trust me...this is possible. I was 28 when I had my daughter and never exercised and HATED to sweat as well. Now I love to exercise. Well, maybe not love, but I enjoy it to an extent.
I also had gone to a plastic surgeon who suggested I try to exercise and lose it before resorting to drastic measures like surgery.
So basically cardio and crunches and the pooch will go away. Good luck.
