Weight-bearing exercises, such as strength training and high-impact activities like jogging or jumping, are best for improving bone density. These types of exercises create mechanical stress on the bones, stimulating bone formation and reducing the risk of osteoporosis as people age. Activities like dancing, tennis, or resistance training can also yield beneficial effects. Importantly, combining these exercises with adequate intake of calcium and vitamin D is essential for optimizing bone health. Regular physical activity is crucial for maintaining strong bones throughout life.
