You'll start just wearing the STIM-FIT empowered electronic Waist Trainer , laying on your couch , sitting on your desk or walking around with simple movements working with your own strength resistance to get those ab muscles activated.

Then, day by day, you'll build on that with more progressive movements . You may also take your CoreWrap to the gym or yoga studio, on a hike, dog walk or playing with your kids.

The workout moves will be fun and challenging (yes, you will feel your muscles burn!), but these short workouts integrating fitness into your daily lifestyle and activities really fly by  and afterwards you will  feel more focused, energized and invigorated, smiling throughout.

Even with a super busy schedule, all you need to get those beautiful toned abs  is 15 minutes a day , that’s the time you put on your CoreWrap and Roth on the automated 12 min. Toning program.

And anyone can spare 15  minutes a day for themselves, getting a super deep massage, can't they? You cab also still keep doing what you gotta do, without missing out on your ab workout, just turn it on!
