The Challenge: Precision Without the Lab
As a Clinical Exercise Physiologist, Laura McDonald wanted to move beyond estimates and field tests. She knew her clients could benefit from real, individualized metabolic data—but traditional lab equipment was costly, cumbersome, and inaccessible to the average client.
Without it, training and nutrition plans lacked the personalization required to deliver consistent, measurable progress. What she was looking for was a tool that could eliminate the guesswork and provide clear, actionable metrics to guide smarter training and lifestyle decisions.
Before, it felt like we were making educated guesses with calculations and field testing. I wanted a tool that could show people exactly how their body responds to exercise and fuel—taking the guesswork out of training and lifestyle modifications.

Client Results: Making Athletes Out of Everyday People
VO2 Master Testing has shown E2O clients what’s possible when consistency meets good training. Many who never considered themselves “athletes” are now putting up impressive numbers and tracking long-term progress.
One standout example is Jen, a 39-year-old mother of two living with Type 1 Diabetes. Active in her community and committed to her health, Jen surprised herself during her first VO2 max test:
- 39-year-old mom of two with Type 1 Diabetes
- Daily walker & cyclist with her family
- First VO2 Max test: 50.8 ml/kg/min
- Ready to retest in 6 months with even bigger goals
VO2 Master has become a cornerstone of E2O Denver’s business model—strengthening client trust, boosting revenue, and elevating results.
If you’re serious about offering next-level, data-driven coaching, it’s a no-brainer. One of the best investments I’ve made for my clients and my business.
