Generally, the larger you are, the more calories you burn during exercise. The number of calories your body uses during physical activity and at rest is called your basal metabolic rate, or BMR. Body size and composition largely determine your BMR. Men who typically have larger bodies and more muscle than women burn more calories during exercise and at rest than women, explains MayoClinic.com.
The more you weigh, the more calories you burn regardless of the type of exercise. In one hour, a 160-pound person burns nearly 600 calories jogging 5 mph, while someone weighing 240 pounds burns about 870 calories doing the same exercise for the same amount of time. A 200-pound person would burn 630 calories per hour ice-skating compared to only 511 calories in a 160-pound individual. Thirty minutes of weightlifting would use up 133 calories in a 185-pound person, but only 90 calories in someone weighing 125 pounds. Spending 30 minutes performing yoga stretches burns 149 calories in a 155-pound person and 178 calories in for someone who weighs about 20 pounds more.
