Peter Attia spends ~3 hours per week in zone 2 (he does so with 4 separate 45-minute cardio sessions). In this video, expect to learn:

• How far into a cardio session you should be before measuring lactate to determine if you're in zone 2 (and the lactate level to look for)
• The lactate meter Peter & Rhonda use
• How to determine if you're in zone 2 using the "talk test"
• Which is better for assessing zone 2: rate of perceived exertion or lactate?
• How to determine if you're in zone 2 using heart rate
• The app Peter checks every morning that predicts his zone 2 as a result of his heart rate variability
