Jack Up Weight Loss
Another fitness expert, registered dietitian Joy Bauer of TODAY, recommends jumping jacks to boost calorie burning. As part of her Weight Loss Challenge program, she prescribes 100 jumping jacks done three times daily as an effective method for burning an additional 60 calories. If you are trying to lose a pound a week, that 60 calories can go toward the 500 calories you need to cut daily to meet your goal.
