In PROVRBS, what does the first R stand for?

• A. Reliability.
• B. Repeatability.
• C. Regularity: maintaining consistency with exercise.
• D. Rigidity.

Answer: (C)

Regularity means maintaining a consistent training schedule and sticking with the exercise plan over time. In PROVRBS, this consistency provides the repeated, predictable stimulus the body needs to adapt. Without regularity, progress stalls because the body doesn’t receive a steady buildup of training stress across days and weeks.

Reliability and Repeatability are terms from measurement and testing, not how you structure training, so they don’t fit as the meaning of the R in this framework. Rigidity implies inflexibility, which contradicts the idea of steady, ongoing training that still allows progression and variation. Regularity is the best fit because it anchors the entire training process with consistent effort and frequency.
