<span>These two components are different sources
of work-out routines in the fitness industry. Each person may dominantly
develop either one of the traits and not both. Some runners are born with the
muscular endurance while body builders don't have this in their genetic
material. Improvements in both could be possible through proper training
regimen and the result of each affects the other. One cannot simply have
muscular strength without first developing muscular endurance. Simply put, you
cannot lift a 100 lb barbell if you are not able to lift a 20 lb barbell
repeatedly. </span>
