Question

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

Answer 1

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

Answer 2

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.
