Weight training
Weight training also provides functional benefits. Stronger muscles improve posture, provide better support for joints, and reduce the risk of injury from everyday activities. Older people who take up weight training can prevent some of the loss of muscle tissue that normally accompanies aging—and even regain some functional strength—and by doing so, become less frail. They may be able to avoid some types of physical disability. Weight-bearing exercise also helps to increase bone density to prevent osteoporosis. The benefits of weight training for older people have been confirmed by studies of people who began engaging in it even in their eighties and nineties.
