I have been using the basic step and now the body fusion along with the ab w/stability ball 4 over 2.5 mnths. I haven't lost any weight. I don't eat bad. I'm 5ft 105Lbs. I'm getting married in a few mnths & would like to lose like 8 lbs or at least have my arms and stomach toned. What other workouts should I do to help me accomplish this?
