Thank you for the opportunity to help you with your question!
Muscular endurance refers to the ability to perform a specific muscular
action for a prolonged period of time. For example, your ability to run a
marathon or to pump out 100 squats with no added weight is due to
muscular endurance. Muscular strength is a muscle’s capacity to exert
force against resistance. Your ability to bench press a barbell weighing
200 lbs. for one repetition is a measure of your muscular strength.
