Three Metrics To Test Fitness Motives
- Work out to defeat sin, serve others, and glorify Christ rather than for self-exaltation.
- Check motives regularly so fitness becomes stewardship, not an idol.
Discipline Fights Sin But Tempts Boasting
- Discipline can fight enslaving impulses like laziness and ease when pursued biblically.
- Boasting in self-discipline corrupts victory, so humility must guard progress.
Train To Be More Useful To Others
- Aim for fitness that makes you more useful in serving temporal and eternal needs of others.
- Avoid training primarily to be seen or praised by people.
