Get A The Protocol Guide: https://korr.com/go/metabolic-testing-protocol-guide/

Ever wonder why a client's VO2 max result seems "off" — or why two tests on the same person produce wildly different numbers? The answer almost always comes down to protocol design. In this episode of Metabolic Mastery, Dr. Marc Humbert and Dr. Cameron Garber walk through a practical, step-by-step algorithm for choosing the right metabolic testing protocol for every type of client — from the completely deconditioned to the elite competitor.

You Will Learn:

• The single most important principle in metabolic testing: how to "test what you intend to measure"
• How to assess a client's fitness history and goals to determine the right testing mode (cycling, treadmill, rowing, hiking, and more)
• Why protocol choice directly impacts the accuracy of VO2 max, heart rate zones, and substrate utilization data
• A watt-by-watt breakdown of cycling protocol progressions (10W to 30W increments) matched to fitness level and gender
• Treadmill protocol design for walkers, joggers, runners, ruckers, and elite athletes — including how to handle the "awkward zone" between walking and jogging
• When and how to run a submaximal test safely, and how the CardioCoach extrapolates VO2 max from incomplete efforts
• How to adjust protocols on the fly without compromising your data
• Why standardizing your decision-making process (not your protocol) is the key to consistent, comparable results across retests
• Equipment considerations — why walking pads fall short and what treadmill specs actually matter
• How strength training history informs both protocol design and exercise prescription

Whether you're just starting out with metabolic testing or looking to tighten up your workflow, this episode gives you a repeatable framework you can apply immediately with any client.
