Yes doing any physical activity burns calories! But stretching does not burn as many calories as jogging or even walking.
That sounds like you have an eating disorder and could lead to passing out. Your body needs calories to sustain that kind of strenuous activity.
OF course:) Any form of exercising burns calories. You even lose weight when your sleeping. You can find a online calculator to find how many calories you burn per however many minutes of jogging ;)
Yes, they are.
Do intense activity, cycling, jogging, etc.
400 to 600 calories sometimes more
2 a minute
jogging for like 10 minutes will burn as much as 100 calories, so if you will try to jo for 30 minutes that will be more or less 300 calories all in all, and it depends on the intensity of your jogging, but you must have a good condition of LUNGS in order to jog for 30 minutes because a lot of oxygen will be needed by the body when we talk about cardiovascular exercises.
Well a jelly doughnut will probably be around 400 calories. 1 hr and a half of jogging burns about 500 calories. So probably quite a while of walking. Jogging is the best option :)
