Adherence

Increasing physical activity from a sedentary lifestyle to an active one in middle adulthood significantly reduces the risk of coronary events compared to remaining sedentary.

If you have been inactive, starting to exercise in middle age still provides significant protection against heart disease. You do not need to have been active your whole life to benefit; the key is to transition from sedentary to active.
