Answer: (B)

Exercise is the term for purposeful physical activity that is planned, structured, and repetitive to improve or maintain fitness. This definition highlights the deliberate planning and regular repetition aimed at enhancing aspects like cardiovascular endurance, muscular strength, and flexibility. It’s a systematic activity you design and follow to gain or maintain fitness over time. The other terms describe different ideas: biofeedback involves training to control bodily functions using real-time data from sensors; reflexology is a therapy based on stimulating specific points on the feet or hands; Reiki is a practice centered on channeling energy for healing. Understanding this helps when advising patients on safe, effective activity plans and documenting exercise prescriptions.
