All of the Wii Fit exercise platforms can help; but she must understand its limitations. If she will invest 45 minutes per day in cardio style exercises she probably will lose some of the fat, depending on diet. As a Fitness Trainer, I see too many failures from home gyms, and many unhappy folks. Of all the home gym investments you can buy, a pair of good walking shoes, is the best investment. Walking and swimming, two of the best exercises available. I admire her willingness to "get with it." She sounds driven, and will probably be successful. A final tip - she needs to start with some light weights, keeping the bone mass solid. I wish her only the best in her efforts.
