This area is designed to provide you with an overview of the considerable amount of research in older adult fitness that has been conducted using Keiser strength training equipment. As you would expect, progressive strength training significantly improves muscle strength and endurance. However, prominent researchers are finding many other benefits as a result of strength training.
