Weight-bearing exercises, such as strength training or high-impact aerobics, are beneficial for maintaining and improving bone density. These types of exercise stimulate bone formation and help to slow down age-related bone loss. Activities like lifting weights, dancing, or running promote the deposition of minerals in bones, thus enhancing their strength and structure. Additionally, maintaining a balanced diet rich in calcium and vitamin D complements the benefits of exercise for bone health. Regular weight-bearing activities are essential for lifelong bone density preservation.
