Some people think that fitness means being able to survive a cardio exercise for an hour without feeling so washed out. They think that fitness has something to do with being strong and flexible. They think fitness is being slim and physically attractive.
All the definitions taken as a whole can best describe fitness but each of these definitions should not be taken as it is. This is what is meant by defining fitness in terms of the whole and not just based on the parts.
Fitness is having all those characteristics in balance
Fitness is having all those characteristics in balance. It is like being strong but with flexibility. It is having endurance but with strength. It can also mean being slim but not just necessarily so.
Fitness is characterized by strength of the muscles, aerobic and muscular endurance, being flexible and the overall composition of the body.
A person who possesses aerobic endurance is one who is able to perform various exercises targeting different parts of the body at a specified period of time. This can include walking or running exercises that require a good use of oxygen. A person who can do prolonged aerobic low-impact exercises is able to break down more carbohydrates thereby getting more strength and energy in the process.
