People who want to lose weight may need to do as much as 300 minutes of moderate-intensity cardio per week, notes Drugs.com. This can burn a significant number of calories. For example, a 160-pound person who runs at a 5-mile-per-hour pace for an hour burns 606 calories. If that same person jumped rope for an hour, he would burn approximately 861 calories, while a more moderate exercise like a leisurely bike ride would burn about 292 calories per hour. Each pound of weight loss requires you to create a 3,500-calorie deficit, so you need to either eat 500 fewer calories daily or burn 500 more calories through exercise each day to lose weight at a rate of 1 pound per week. - See more at: http://www.livestrong.com/article/313665-calories-burned-in-one-push-up/#sthash.8hFzAGBc.dpuf
