Summary: The ability of the body to burn calories while sitting down is dependent on personal body fat composition. Find out how people with larger muscle mass will burn more calories sitting down with information from a fitness trainer in this free video on health and staying in shape.
"So you are just sitting around and you're doing nothing or you could be watching TV or just hanging out but you know what you are still burning calories. I'm Carol Ann with Studio Group X and we're going to talk about how many calories you can burn just by sitting down. Now we are all different people, different bodies made up of different muscle mass tissue, body fat, so it depends on what your body fat composition is in terms of how many calories you are going to burn at rest. So if you've got a more muscular person they're going to be a constant metabolism machine burning a lot of calories than someone who doesn't have a lot of muscle mass. So let's just take the average person. Just by sitting down a male weighing about 190 pounds will burn about 90 calories an hour. Now take an average female weighing about 135 pounds and she is going to burn about 65 calories an hour just by sitting. Now let's just change things up a little bit. If you were to be sitting on an unstabled surface now your body has to work at maintaining great posture so even though you are sitting you have got a lot going on internally, working those core muscles, burning a lot more calories so just go from a stabled position like a chair, put yourself on a stability ball and you're going to burn way more calories. I'm Carol Ann with Studio Group X and we just talked about how many calories you just burned sitting down. But I encourage you get that stability ball out, work it more and burn more calories."
