Chronic illness can significantly impact fitness capabilities, often leading to limitations in physical activities. Conditions such as diabetes, arthritis, and heart disease may necessitate tailored exercise programs to accommodate individual needs. Patients often face reduced energy levels and mobility issues, hindering their ability to engage in regular fitness routines. Additionally, chronic illnesses can lead to psychological challenges, such as depression, which may further affect motivation. Adapting fitness goals and emphasizing safe practices is essential for managing health in such circumstances.
