Muscle strength is the largest amount of force a muscle can produce with one movement, like throwing or kicking a ball as hard as you can.

    Muscle endurance is how long a group of muscles can work with out stopping, like hanging by your hands on a playground bar as you move along the bar or doing sit-ups for a long period of time.

    You need both muscle strength and muscle endurance to stay fit.
 
 

    Building your muscles to be strong and active takes time. If you exercise your muscles they get strong and help you to be healthy and fit. If you don’t use your muscles they get weak.

    Compare this to the life of a plant. A plant gets strong when it gets plenty of air, water, and
sun.If the plant doesn’t get these three things it will become very weak, just like your muscles.
 
 

Let's take a look at your Muscles.

Use the diagram above and see if you can locate the following muscles:

Deltoids-located in the shoulders

Pectorals-located in the chest

Abdominals-located in the stomach

Bicep-located in the front of the upper arm

Tricep-located in the back of the upper arm

Quadricep-located in the front of the upper leg

Hamstrings-located in the back of the upper leg

Calves-located in the back of the lower leg
 
 

Abdominals-Domino's Pizza!If you eat pizza
        it will go to your stomach.

Deltoids-Delta Airlines! Muscles in the
        shoulders make your arms go up and
        down in order to fly.

Pectorals-A Gorilla! A Gorilla hitting their
        chest.
 
 

    You could not move without muscles. You need muscles to move your bones so you can run, walk, dance, climb, lift, throw, push, and pull. You need muscles to smile, to wink your eye, and to scratch your nose.

    Your tongue, heart and stomach are all muscles. Muscles help your lungs move air in and out of your body so you can breathe.
