Muscular Endurance

Muscular Endurance: Muscular endurance is the ability of a muscle or group of muscles to sustain repeated contractions against a resistance for an extended period of time

High repetitions with low resistance : Like when you're running, or riding your bike down hill. Swimming is another. 

Sport specificity: This is the principle of training; that sports training should be relevant and appropriate to the sport for which the individual is training in order to produce a training effect. 

You wouldn't go to a soccer game to be a good tennis player

work/rest ratio : It would depend on what I am trying to do. In a 24 hour ratio it would be about 2:22 ratio if the goal was to keep muscle endurance. 

How can I include these concepts in my life? 
Instead of parking right next to the grocery strore, I would park father away so I would need to walk. And instead of driving up to the mail box on my way home, I would walk to the mail box and back. Exersizing more with the little things in life.
