Lactate Thresholds, The Key to Smarter Endurance Training
What Are Lactate Thresholds?
Lactate thresholds (LT1 and LT2) are critical markers in endurance performance. They indicate how efficiently your body processes lactate—the byproduct of energy production—during exercise. Understanding these thresholds helps you train smarter, avoid fatigue, and optimize performance.
By training at and around these thresholds, you can build endurance, increase speed, and delay fatigue.
LT1
Aerobic Threshold
The point where lactate begins to rise above baseline, marking the transition from easy, sustainable effort to moderate intensity.
Why Do Lactate Thresholds Matter?
Unlike heart rate zones or perceived exertion, lactate thresholds provide direct physiological insight into your endurance capacity. Training based on LT1 and LT2 helps you:
✅ Optimize Zone 2 Training – Improve fat metabolism and aerobic efficiency.
✅ Increase Power & Speed – Push LT2 higher, allowing you to sustain harder efforts for longer.
✅ Train Smarter, Not Harder – Avoid overtraining by balancing intensity and recovery.
