Which of the following is an example of a low-impact exercise?

Swimming is considered a low-impact exercise because it places minimal stress on the joints while still providing an effective cardiovascular workout. The buoyancy of water supports the body, reducing the impact that joints experience compared to activities performed on solid ground. This makes swimming an excellent choice for individuals who might have joint issues, are recovering from injuries, or simply prefer a gentler form of exercise. It allows for a full-body workout while minimizing the risk of injury associated with high-impact activities like running or jumping rope.
