She began her career as a fashion model, at which she was successful until contracting a bad case of pneumonia, which caused her to lose a lot of weight. Soon after her recovery, she began training with weights to regain the weight she needed to get back to modelling. After achieving a somewhat toned build, she was rejected at model agencies for being oversized. She then decided to give up modeling and dedicate herself to bodybuilding. During her bodybuilding career Sharon had gained nearly 50 pounds, but then cut back when she changed to fitness competitions.[5] Bruneau was on the cover of Muscle & Fitness and Flex.[when?]
