My mother, 52 years old, is obese, and has finally asked me to help her lose weight and get healthy again. First thing we did is clean up her diet, mostly by following Berardi and the FAQs, slowly introducing her to better foods etc, and she is starting to lose weight slowly but surely. She now wants to take up exercise to speed the process along. She doesn't want to go to a gym, or a personal trainer, as she doesn't feel comfortable with that, and I want to help her before she gets any older. She has access to a treadmill, rowing machine, boxing bag, skipping rope, barbells and dumbells. Where should I start with her? Would walking be a place to start? Any advice please, the doctor has told her she's borderline diabetic and needs to lose weight and exercise NOW!
