The fifth and last of the five components of physical fitness is the body type. This component is variable, since it depends upon the individual. Someone who is large and muscular has a different composition than someone who is dainty or petite. Bone structure, genetics, and even gender can play a role in this part of the five components of physical fitness. You have to remember to take this last component into consideration when tailoring a workout for yourself. A petite size zero lady would embark upon a very different routine than a male body builder.
