Which fitness component is best described as the ability to hold a position or repeat a movement many times?

• A. Flexibility
• B. Cardiovascular Fitness
• C. Muscular Endurance
• D. BMI

Answer: (C)

Muscular endurance is the ability of a muscle or muscle group to sustain repeated contractions or to hold a position for an extended period. When you can hold a position like a plank or keep performing repetitions of a movement without fatigue, that shows muscular endurance. This differs from flexibility, which is how far a joint can move; cardiovascular fitness, which is the body's ability to supply oxygen during prolonged activity; and BMI, which is just a measure of body mass relative to height and doesn’t reflect how long you can work a muscle. Muscular endurance sits in contrast to muscular strength, which is about the maximum force you can produce in a single effort.
