High CR fitness generally means the individual performs physical activity, which is associated with health benefits.

Increasing CR fitness is associated with reductions in all-cause mortality.

Deconditioned individuals have a higher risk of premature death than conditioned individuals.

The ability to perform large muscle, dynamic, moderate-intensity exercise for prolonged periods of time.
