Mini Bio (1) Heidi Klum was born in Bergisch Gladbach, a small city near Cologne, Germany, in 1973. Her career as a top fashion model and swimsuit star began almost by accident when, on a lark, she submitted photos to a model competition hosted by Petra, a young woman's magazine.
Adults should engage in weight training at least two times a week, recommends the Centers for Disease Control and Prevention. You can always increase the number of days you train with weights as long as you give each muscle group three days of rest before training it again. Opting to increase this to three or four days will help you to reach your goals more quickly, as you will burn more fat and calories.
Weight Watchers recommends that you weigh yourself once a week, while some dieting sites suggest throwing away your scales so as not to become demoralised. Scales can seem extraordinary fickle at times, with weight fluctuating by nearly 1kg from day to day.
