Fit for Eternal Life by Kevin Vost

Below is only the quotes and sections I found relevant. I left out the sections on proper exercises and workout routines.

“Or know you not, that your members are the temple of the Holy Ghost, who is in you, whom you have from God; and you are not your own? For you are bought with a great price. Glorify and bear God in your body.” – 1 Corinthians 6:19-20

God gave us our body as a most precious gift, and it is our Christian duty to care for it – indeed, to perfect it.

“There is a need to find free time in order to exercise strength and dexterity, endurance, and harmonious movement, so as to attain or guarantee that physical efficiency necessary to man’s overall equilibrium” – Pope St. JPII

The goal of this book is to make fitness a good habit: a virtue.

Virtue lies between the vices of extremes, between deficiency on one side and excess on the other. This is a golden peak that towers between two extremes.

Every virtue is a kind of habit. Virtues are habitual patterns of thought and behavior that dispose a person to the proper use of his powers. And we acquire virtuous acts by performing them. And virtues, when developed, make it easier for us to make the right choices.

The framework for this book will be based on the cardinal virtues: prudence, fortitude, temperance, and justice. Cardinal is based on the Latin word cardo meaning “the hinge of a door” for all other virtues hinge on them and can’t operate fully without them.

True physical progress, like spiritual progress, is made through radical self-giving, through seeking out difficult challenges. Our fallen human nature naturally draws us toward leisure and easy pleasures, being satisfied with a lame mediocrity.


“Unless we first tame the enemy dwelling within us, namely, our gluttonous appetite, we have not even stood up to engage in the spiritual combat.” – St. Gregory the Great

Gluttony can include eating hastily, sumptuously, too much, greedily, and daintly (thinking too much about it).

Seeking excess comfort for our bellies makes us less apt to imitate Christ through suffering and sacrifice.

Exercise does not exempt you from dietary temperance and prudence either.
