Working out consistently facilitates your weight loss efforts. To lose weight, you must burn more calories than you consume. The calories you burn from riding an elliptical trainer or a bike add to the total number of burned calories.
The calories that you will burn when riding an elliptical or a bike is dependent upon the intensity and duration of your workouts, as well as your own personal body weight. The longer and harder you work out will have a direct impact on the number of calories you burn. Heavier people burn more calories in the same amount of time as smaller people.
According to Health Status, a 150 lb. person will burn about 774 calories for every hour spent on an elliptical trainer. You can calculate an estimation of calories for your specific weight by using an online calorie calculator.
Health Status calculates that a 150 lb. person will burn about 594 calories when riding bike at 12 to 14 mph for 60 minutes, but will burn about 720 calories during that time if riding at 14 to 16 mph.
