Wear a weighted belt or hold a dumbbell between your feet (as shown here) and grab onto a pullup bar with palms facing away from you and hands wider than shoulder width. Allow your body to hang . Pull yourself up until your collarbone touches the bar and your shoulder blades are squeezed together . Lower yourself back to the starting position. That's one rep.
