I would suggest an olympticial trainer 20 min. a day for the cardio. It burns more and works the legs, Maybe pilates too. Write down everything you eat, drink and exercise and see if they balance. YOu might just need to be keeping track of what you do and amounts of food for a start. THe other activities sound good, Check with your doctor but I would think that adding these won't hurt. THat hip should be set by now an increasing you activity level wouldn't hurt.
