After her ICD implant, doctors told her that she could not exercise at all, but Carney found that not exercising made her heart worse and that instead it was better to exercise a little every day to keep it under control. She then found that she could do "quite a lot" of training, provided she avoids damaging high-intensity spurts. For example, she completed an iroman-length (180 km) bike ride, and hopes eventually to complete a full iron-distance race. Occasionally, she exercised too hard, causing her ICD to "shock" her heart, as happened once when she was out running with her father. It also happened in 2008 when she was taking part in the 299 km Melbourne-to-Warrnambool bike race, when she forgot about her condition and attempted to chase down the leading pack.
