What term refers to the practice of healing or improving health through physical means, such as exercise?

The term that refers to the practice of healing or improving health through physical means, such as exercise, is "therapeutic." This term encompasses a wide range of activities and interventions aimed at restoring or enhancing health and well-being through methods that may include physical activity, manual therapy, and other forms of exercise. Therapeutic practices can help alleviate symptoms, improve function, and promote overall health.

In this context, preventative refers to measures taken to prevent health issues before they arise, while diagnostic pertains to the identification of diseases or conditions through tests and assessments. Rehabilitative focuses specifically on the process of recovery after injury or illness, which may include therapy and exercise but does not encompass the broader range of physical health improvements that the term therapeutic includes. Thus, "therapeutic" is the most appropriate term for the practice of healing through physical means.
