Weight-bearing exercises, such as strength training, running, and jumping, are integral for improving bone density. These exercises apply stress to bones, stimulating bone remodeling and strengthening them over time. Especially important during youth and aging, increased bone density helps reduce the risk of osteoporosis and fractures. Incorporating a variety of weight-bearing activities is vital for maintaining healthy bones and enhancing overall skeletal health, enabling individuals to stay active and independent as they age.
