Put on your ankle weights. Sit on a stool or the edge of a sturdy and secure table or desk. Slowly straighten first one leg, then the other. At the top of each lift, when the leg is straight, pause for a breath or two. Be sure to let each leg back down slowly. Keep your back straight. Repeat 10 to 15 times each leg. In a gym, look for the "leg extension machine" for the same workout.
