metabolism and aerobic system
test at muscle level with a Moxy sensor
aerobic use is a dial, not an on/off switch
testing VO2max
- Cooper Run or 2K on Rower
- compare to the population
Template MWF = lifting: Cardio T, Th, maybe Sat
Modality, start with a bike if you have the option, less depletion of O2 overall
In the Phys Flex Course, I go over pH and O2 / CO2 mechanics and how to program for it

This podcast is brought to you by the Physiologic Flexibility Certification course. In the course, I talk about the body's homeostatic regulators and how you can train them. The benefit is enhanced recovery and greater robustness. We cover breathing techniques, CWI, sauna, HIIT, diet, and more. Sign up for the waitlist, and you'll be notified as soon as the course opens.
