In addition to helping you stay lean and strong, a whole-body workout that includes resistance training will help strengthen your bones. The National Institutes of Health (NIH) Osteoporosis and Related Bone Diseases National Resource Center reports that regular exercise is essential for treating and preventing osteoporosis. Bone is living tissue that can be strengthened with weight-bearing and weight training exercises. Exercising also helps us maintain muscle strength, coordination, and balance, which in turn helps to prevent falls and related fractures.
