Strength training positively impacts bone density by stimulating bone remodeling through mechanical stress. When resistance is applied, bones adapt by increasing their density and strength, reducing the risk of osteoporosis and fractures. High-impact and weight-bearing exercises, such as squats and deadlifts, are particularly beneficial for promoting bone health. Regular strength training combined with adequate calcium and vitamin D intake can significantly enhance bone density, contributing to long-term skeletal health and overall physical well-being.
