Muscular endurance refers to the ability of a muscle or group of muscles to sustain repeated contractions over an extended period. This is essential for engaging in activities that require prolonged physical effort, such as running, cycling, or participating in sports. Enhanced muscular endurance enables individuals to perform daily tasks more efficiently and reduces the risk of **injury**. Training for muscular endurance typically involves higher repetitions with lighter weights or bodyweight exercises, promoting overall strength and improving functional fitness for various physical activities.
