Living an active and healthy life is my advise to all of my patients once they have recovered from their procedures. Switch up your exercise regimen but make sure it always incorporates strength training, cardio/aerobics, and stretching; such as yoga. If you like doing outdoor activities, you can substitute some of your workouts with things such as hiking, walking, etc.
As far as your diet goes, everyone is different, but make sure you are eating nutritious foods, and if you need further advice you can seek the help of a nutritionist. Best of luck to you.
