Family Medicine in Austin: Fifth Principle of Conditioning

It’s time for another Austin-area family medicine 101 class!

There are six principles of conditioning in the field of exercise science that every athlete or trainer should follow when prepping for the optimal workout or exercise program. These principles are universally accepted and should be followed so that those participating can make the most gains and improvements in their fitness and performance levels.

The fifth of the six principles is the Principle of Use/Disuse. This principle implies that when it comes to fitness, you either “use it or lose it.” It simply means that your muscles hypertrophy with use and atrophy with disuse. This also explains why we lose fitness levels when we stop exercise.
