Which of the following examples is NOT considered a weight-bearing activity?

Swimming is the activity that does not qualify as a weight-bearing activity. In weight-bearing exercises, the body must support its own weight against the force of gravity. Activities such as wall push-ups, chair push-ups, and squats require the muscles to work against gravity and support the body's weight, thereby helping to maintain or improve bone density and overall strength.

In contrast, swimming takes place in water, which provides buoyancy that reduces the strain on the body. This means that while swimming is excellent for cardiovascular fitness and joint mobility, it does not exert the same impact on the bones as weight-bearing activities do. Thus, swimming is classified as a non-weight-bearing activity.
