Why Retesting is the Secret to Long-Term Results

One-time tests tell you where you are. Retesting tells you where youre going—and how to course-correct if needed.

At Plus10, we believe progress should be objective. That’s why retesting isn’t just an option—it’s a pillar of how we work. Whether it’s body fat percentage, lactate threshold, or VO2 max, regular check-ins ensure that your plan evolves with you.

VO2 max, for example, is a powerful predictor of cardiovascular and all-cause mortality. A 2018 study by Laukkanen et al. published in the Mayo Clinic Proceedings found that low VO2 max levels were associated with a 5-fold increase in risk of death from all causes, regardless of age or other risk factors [1].

Retesting also helps detect plateaus or regressions early. According to a 2023 paper in Sports Medicine by Jones and Thompson, athletes who tested lactate thresholds every 6–8 weeks improved performance by 12–18% more than those who trained without retesting benchmarks [2].

Retesting eliminates the guesswork and lets us adapt your program with precision. Seeing measurable improvements isn’t just motivating—it’s empowering. It’s how we ensure our clients stay on track, stay committed, and stay healthy for the long haul.
