#492 Jason Brown - In Defense of Zone 2 Cardio

#492 Jason Brown - In Defense of Zone 2 Cardio

Author: Andrew Coates August 4, 2026 Duration: 57:33

Jason Brown returns for a nuanced discussion about Zone 2 cardio, walking, conditioning, stress, recovery, and how cardio should fit into an individual’s life.


Jason joins me to discuss:


• Whether Zone 2 cardio is actually overrated

• How much of Zone 2’s benefit comes from simply getting people moving

• The value of reducing sedentary time and increasing daily activity

• The relationship between Zone 2-style activity, NEAT, and mental health

• Why getting outside and moving can provide benefits beyond fitness adaptations

• Looking at cardio and all training through the lens of nervous system regulation

• Accounting for the total stress already present in someone’s life

• Why cardio recommendations should begin with the individual’s available time and capacity

• The nuanced debate around whether walking counts as exercise

• Why sprint training should not be treated as Zone 2 cardio

• Why average heart rate during lifting or high-intensity training does not prove someone received a Zone 2 stimulus

• The difference between cardiovascular strain and sustained aerobic work

• Why exercise labels matter less than matching the activity to the person’s needs

• Jason’s thoughts on the current state of online coaching

• And much more
