Evaluate your current health, as well as physical capabilities and limitations. Talk to your doctor. Get a general medical evaluation with special attention given to the cardiovascular, breathing, muscular and nervous systems. Understand and clarify your training goals. A primary goal of many older exercisers is to maintain an independent lifestyle that allows participation in all the activities they enjoy.
Exercise is part of the solution, along with diet, adequate rest and a positive outlook.
Adjust your cardiovascular training. The generally recommended frequency for aerobic conditioning is three to six times per week. Cardiovascular improvements have been shown with easy to moderate levels of intensity. This will put less stress on your heart, muscles and joints. This may be the most important step in slowing the aging process.
