When the weight returns, it comes back as fat. To avoid getting fatter over time, increase your metabolism by exercising regularly. Walking is one of the best exercises for strengthening bones, controlling weight, toning the leg muscles, maintaining good posture and improving positive self-concept. To lose weight, it's more important to walk for time than speed. Walking at a moderate pace yields longer workouts with less soreness - leading t more miles and more fat worked off on a regular basis.
High intensity walks on alternate days help condition one's system.
But in a walking, weight-loss program, you are not required to walk an hour every day as some people would have you believe. When it comes to good health and weight loss, exercise and diet are inter-related. Exercising without maintaining a balanced diet is no more beneficial than dieting while remaining inactive.
