Evidence has been emerging on the importance of adding a muscle-strengthening component to regular physical activity to improve quality of life; delay the loss of muscle mass and function; and prevent osteoporosis, sarcopenia, and the falls, fractures, and disability that may follow.1 Menopause and aging may lead to a loss in fitness, decrease in muscle strength and bone mineral density, and a gain in weight, all of which concomitantly increase the risk for many chronic diseases, such as cardiovascular disease.2 If muscle-strengthening exercise can delay or prevent these diseases in postmenopausal women, this would have important public health implications.
