πŸ’‘ What is Zone 2 Training?

Zone 2 is the aerobic 'conversation pace' zone β€” 60-70% of heart rate reserve (Karvonen method). At this intensity, your body primarily burns fat for fuel while building mitochondrial density and cardiovascular efficiency.

The Maffetone (MAF) method uses a simpler formula: 180 βˆ’ age. This approximates the top of Zone 2 for most people. Zone 2 training has gained popularity through advocates like Dr. Peter Attia as a longevity strategy.

Age 30, resting HR 60: Max HR = 190, Zone 2 = 138-151 bpm. MAF = 150 bpm.
