Max Heart Rate & Cardio Zones

Calculate target heart rates for cardio training splits.

Cardiovascular Zone Training

Training in specific heart rate zones optimizes target metabolic pathways. By identifying your Maximum Heart Rate (estimated as $220 - \text{Age}$), you can structure cardio intervals for maximum results:

The 3 Crucial Cardio Zones

  • Fat Burn Zone (60% - 70% of MHR): Ideal for long steady-state aerobic base development, utilizing fat reserves as primary energy.
  • Aerobic Endurance Zone (70% - 85% of MHR): Strengthens cardiovascular performance, increases capillary networks, and lung volume.
  • Anaerobic Lactic Zone (85% - 95% of MHR): High-intensity efforts that improve power output and lactic acid clearance rate.
