is that all? how do i burn more calories??

If your burning calories Im assuming you wanting to lose weight. All those other suggestions are good also try swimming. The thing is what about your food intake. make sure you are eating. if your not eating enough or the right stuff your body will adjust itself to a bad motabilizim. Try adding 1/2 cup pineapple juice a day and 1/2 cup of brocolli or 1/2 cup spinage or carrots twice a week That worked for me . Lost 30 pounds in 3 months. kept if off for a year now.
