Chronic illness can dramatically affect fitness levels due to its impact on physical, emotional, and mental well-being. Conditions like arthritis, cardiovascular diseases, or respiratory disorders limit physical activity and lead to decreased strength and endurance. Additionally, chronic illnesses often cause fatigue, pain, and mobility challenges, which can create barriers to engaging in regular exercise. The emotional toll of living with a chronic condition may lead to diminished motivation and increased feelings of isolation. Addressing these challenges through supportive measures and tailored fitness programs is crucial for improving overall health and quality of life.
