Peter Attia MD has a great breakdown of Zone 2 training that’s worth watching. This summary captures the essentials so you can run a workout this week—head to the full video if you want the deeper context.

Key insights:

  • Zone 2 feels easy enough to talk during, which puts you around RPE 3-4—the defining feature, not any particular heart rate or wattage.
  • Use how you feel as your guide. Track power and heart rate if you want, but don’t get caught up in hitting exact numbers.
  • Aim for at least three hours of Zone 2 per week. Those starting out can begin with three sessions of twenty minutes.
  • Bike, treadmill, stair climber, brisk walking, running, swimming—Zone 2 works on all of them. The key is keeping the effort steady and comfortable enough that you can still talk.

Workout breakdown:

  • Frequency: Three twenty-minute sessions per week to start, then scale up toward three hours total as you build fitness.
  • Intensity: RPE 3-4 (you’re conversational, but not coasting). If you like data, aim for around 225 W and heart rates in the 130-140 bpm range—though feel takes priority.
  • Duration: Begin with twenty-minute steady sessions, then add time week to week until you hit three hours total per week.

Try out a Zone 2 session this week and adjust the length and pace to what works for you in the Pacing app. You’ll develop a strong aerobic foundation—stick with it and the payoff comes over time.
