Endurance 
Endurance (also called Sufferance, Stamina, Resilience, or Durability) is the ability for a human or animal to exert itself
and remain active for a long period of time, as well as its ability to resist, withstand, recover from, and have immunity 
to trauma, wounds, or fatigue. In humans, it is usually used in aerobic or anaerobic exercise. The definition of 'long' varies 
according to the type of exertion - minutes for high intensity anaerobic exercise, hours or days for low intensity aerobic exercise.
 Training for endurance can have a negative impact on the ability to exert strength unless an individual also undertakes resistance
 training to counteract this effect.
