Before starting an exercise program, talk to your doctor about:
Medication changes. New medications can greatly affect your response to exercise; your doctor can tell you if your normal exercise routine is still safe.
Heavy lifting. Make sure that lifting or pushing heavy objects and chores such as raking, shoveling, mowing, or scrubbing aren't off limits. Chores around the house can be tiring for some people; make sure you only do what you are able to do without getting tired.
Safe exercises. Get the doctor's approval before you lift weights, use a weight machine, jog, or swim.
