Identification. Muscular strength is the ability of the muscles to lift weight. Muscular endurance is the ability to sustain exertion for a specified period of time.
Muscular strength cannot be achieved without muscular endurance. Both are health-related fitness components that depend on each other. When muscles are able to endure bouts of physical exertion, strength is developed; and in the same way that strength cannot be fully achieved if endurance is poor. All athletes must include in their training the development of both to last in their specific events or competitions.
