Because they use them to hop all the time.
Frogs have the same muscles as humans, but some muscles are developed differently than others. They do not have very powerful arms, but the jaw and leg muscles are strong. They also have very flexible tendons so they can leap long distances.
Well, muscular endurance ensures that you are able to keep at certain exercises longer. For example, if you have really good muscular endurance in your arms, it would take more reps (if you were lifting weights) to get your arms to be tired. So the benefit of muscular endurance is pretty much that you can exercise more efficiently because you won't tire out so easily.
Boxers need to have strong muscular endurance in their arms so they can provide force to hit their opponents for long amounts of time.
No not realy , but your arms become strong and muscular.

No tadpoles are 'baby' frogs when tadpoles get older they grow legs and arms then turn into frogs
The same way any muscle works - electrical impulses from the brain stimulate the muscle to move.
there butts grow
put them in a tub of hot water for an hour
activities that require good muscular endurance are activities that require you to work with muscle groups for a longer period of time. eg. swimming- good muscular endurance is needed so that you can maintain a good standard performance all the way throughout and so that your arm stroke does not get weaker/arms get tired. with good muscular endurance, your arms will not get tired as easily and you can keep up strong, fast strokes.
