You did not mention what you are doing for your cardiovascular workout. I would suggest swimming. All movements are resisted, you are only 1/6th your body weight than on dry land which also unloads your joints from the stress that is added when jogging, aerobics, running, etc.

Keep a variety in your workouts too. If you jog, make sure you are changing your route so that your body does not adapt and platueau.

Good luck.
