S1, E1: This ab workout can be a part of a comprehensive plan to lose your belly fat. Spot reduction of fat is a big lie. Exercising your stomach will not make it smaller. In fact, it might make it look even bigger! What does work is any fitness plan that incorporates fat burning cardio five times a week and a resistance training program that works all major muscle groups at least twice per week. This way, you will lose fat all over, trim down your waist, and reveal all your hard work!
