This is another very discreet exercise you can do while waiting in line. While standing on the balls of your feet, clench your buttocks together for three seconds, tightly, then slowly release and go back to the flats of your feet. Repeat for three sets of ten to twelve, with 15 to 30 seconds between sets. This exercise is great for toning your bootie!
