10 lbs in two weeks.?

You can use the elliptical, the tread mill or the stair stepper. It's all about what you put into it. Ex: running a 5 min mile vs running a 9 min mile. One burns way more calories. Another thing you might consider is a nutritional fat-burning and cleansing program. I lost 15 lbs in 10 days with one. A buddy of mine lost 10 lbs in 10 days. If you want more info on that, send me an email. I'll also include some links. Good luck! Enjoy your vacation! They are always better when you look and feel good!
