What aerobic exercise is best for the heart?

Well friend, Aerobic exercise, is when you are exercising within a specific heart rate zone - 70% to 80% of your MHR. This zone is just right for building endurance, and you should be able to maintain this effort for long periods of time, even hours. Anaerobic activity is whenever you are above that zone - 80% to 89% of MHR. Lifting weights is an example, which builds muscle and speed but can only be managed for minutes at a time.

?jogging, brisk walking, swimming, aerobic dance, cycling. These are some but you should have to perform this moderately.
