Weightlifting is known to be a weight-bearing activity that helps build and maintain bone density, thus reducing the risk of osteoporosis. This type of resistance training applies stress to the bones, stimulating bone formation and strengthening the skeletal system.

On the other hand, activities like cycling tend to not be weight-bearing, meaning they do not provide the same mechanical loading to the bones as weightlifting, walking, or running do. While walking and running are also weight-bearing exercises that contribute positively to bone health, cycling primarily engages muscles without stimulating bone density to the same extent.

Therefore, weightlifting is a proactive method for enhancing bone strength and lowering the risk of osteoporosis, making it the best choice among the activities listed that's least associated with the risk of the condition.
