I want to calculate all my heart rate zones.

It seems there are no specific clips from the Huberman Lab that directly address calculating all heart rate zones. However, I can provide you with some general guidance based on common principles used in fitness:

1. Maximum Heart Rate (MHR): Often calculated as 220 minus your age.
2. Heart Rate Zones:
   • Zone 1 (Very Light): 50-60% of MHR
   • Zone 2 (Light): 60-70% of MHR
   • Zone 3 (Moderate): 70-80% of MHR
   • Zone 4 (Hard): 80-90% of MHR
   • Zone 5 (Very Hard): 90-100% of MHR

These zones are used to tailor workouts to specific fitness goals. It’s always best to tailor these calculations with individual fitness levels and, if possible, consult a fitness professional to interpret and apply them to your personal training plan.
