Grip strength might predict older adults at risk for chronic disease or early death. In a new study published in the Journal of Cachexia, Sarcopenia and Muscle, researchers at the University of Michigan demonstrated that grip strength can demonstrate existing muscle weakness, and that this muscle weakness is associated with accelerated biological age. Just as smoking has been shown to predict disease and mortality, the researchers argue that muscle weakness could be the new smoking. To increase your grip strength, the researchers emphasize the need for regular muscle-strengthening activities, like lifting weights, for at least 30 to 60 minutes each week to reduce the risk of cancer, heart disease, and death.
