What are the factors that influence fitness?

The factors that influence fitness are:

  1. Heredity (you can usually look at your parents and grandparents to find out what you will look like in the future. If you don't like what you see, get fit)
  2. Lifestyle choices
  3. Gender (fat storage areas)
  4. Chronic disease (7 out of 10 leading causes of death in America are chronic, caused by poor lifestyle choice, example: alcohol, obesity, tobacco)
  5. Age (it is easier to get rid of fat when you are younger, it gets harder as you get older)
