We are what we eat (apparently) as well as ourgenetics define our success in training to meet health and fitness goals according to some "experts". In that case why do we bother? We bother because we have more control over your life that these findings would suggest, something that is backed up by the study of epigenetics. Those knowledgeable about genetics and all things cell-related will tell you that epigenetics is the study of (in basic terms)  how environmental factors can alter genes (effectively activating them and switching them off) and more.
