I'm not losing weight. Research shows that few people — including the obese — lose weight through exercise alone. One reason: They don't change their diet. "To lose weight, you need to combine regular exercise with consuming fewer calories," says Dan Carey, an exercise physiologist at St. Thomas University in Minnesota. Remember that when you reach for a post-workout reward.
I'm embarrassed to exercise around others. This is especially true among the overweight — and those who go to a health club. Choose a "like-bodied" exercise class or gym and work out with friends for support.
I don't have the time. The goal is 30 minutes daily. But it can be several 10- to 15-minute sessions. Use exercise time to read mail on a stationary bike or make phone calls while walking.
