The most effective type of exercise for improving bone density is weight-bearing exercise. Activities such as running, jumping, or resistance training place stress on the bones, stimulating bone formation and reducing the rate of bone loss. This mechanical load encourages the body to strengthen bones, enhancing overall skeletal health. Strength training also plays a vital role by improving muscle mass surrounding bones, providing added support and protection. Consistent participation in weight-bearing exercises is essential for maintaining bone density, especially as individuals age.
