If you want to . . . Lose weight: Creating a calorie deficit that results in weight loss is hard work. Most recommendations say that to lose weight, you must exercise for at least an hour a day, five times a week. The type of exercise matters, too.
The guidelines suggest anywhere from 20 to 60 minutes of cardio to be healthy, lose weight and get fit, depending on the types of workouts you do. That's fine, but you don't want to start with an hour of exercise. That's just too much for anyone if you haven't exercised for awhile...or ever.
