Understanding Heart Rate Zones for Endurance Training
Heart rate training is key for effective endurance gains.
Understanding your zones helps target specific physiological adaptations:
  • Zone 1 (Recovery): Very light, aids recovery.
  • Zone 2 (Aerobic Base): Builds endurance, fat burning.
  • Zone 3 (Tempo): Improves aerobic capacity, lactate threshold.
  • Zone 4 (Threshold): Near maximal, builds speed endurance.
  • Zone 5 (Max Effort): Short bursts, improves VO2 max.
"Train smarter, not just harder."
