In your own words, what is the difference between muscle strength and
muscle endurance?

Muscle strength deals with the maximum potential of a muscle group to perform. Muscle endurance is more on how long that muscle group can continue performing its task. Strength deals more with a single maximum output while endurance deals more with how long the muscle can last doing an exercise. For example, a single rep max is muscular strength, while doing multiple low-weight muscle exercises is endurance.

Muscle strength is the max out load one can do and muscle endurance is the repetitive movement one can do for long periods of time

Iwould have to go with the last one "have personal value and positive expectations."    hope it : 3 if im wrong tell me
