A client comes to the clinic reporting chronic low back pain. He asks the nurse to recommend specific exercises for him. Which of the following activities should the nurse suggest?

A. Archery does not provide aerobic or strengthening benefits for back pain and may strain the upper body. B. Swimming is recommended because it provides low-impact aerobic exercise, strengthens back and core muscles, and reduces stress on joints. C. Tennis involves quick twisting and pivoting movements that can worsen back pain. D. Canoeing requires repetitive trunk rotation, which can aggravate back pain rather than relieve it.
