Chronic Illness and Exercise: Cutting Through the Misinformation
Chronic illnesses are more common than many people realize, and a significant number of individuals live with more than one condition. In fact, multimorbidity—having multiple chronic illnesses at once—is increasingly prevalent, especially as people age.
