Muscle Strength and Muscle Endurance

Explanation:

All of the above actions define a person’s muscle endurance or strength.  

Muscle endurance is the power or ability to put a specific muscle into action for a long time period. The actions or to do 20 push-ups in a row or to arrange books on bookshelf for a time period demonstrates muscle endurance

Muscle strength is the highest amount of force which a muscle exerts at a particular time in one effort against resistance. Lifting heavy bag, pull-up exercises shows muscle strength.

Simply put, muscle strength repeats an action for less number of times but with increased weight; whereas, muscle endurance repeats action for more number of times but with decreased weight .
