extensieve interval training

Unlike intensive intervals (which target VO2 max or lactate tolerance at near-maximal efforts), focus on improving aerobic efficiency , capillarization (blood vessel density in muscles), and lactate clearance at a comfortably hard pace. They are a cornerstone of base building for runners, rowers, cyclists, and swimmers. 1. What Is Extensive Interval Training? | Aspect | Extensive Interval | Intensive Interval | | :--- | :--- | :--- | | Primary goal | Aerobic development, fat oxidation, stroke volume | VO2 max, lactate tolerance, speed | | Intensity | 75–82% max HR (or 65–75% of HR reserve) | 90–95% max HR | | Lactate level | ~2–3 mmol/L (below lactate threshold) | 4–8 mmol/L (above lactate threshold) | | Work:rest ratio | ~1:0.5 or 1:1 (short rest) | ~1:2 or 1:3 (long rest) | | Feeling | “Comfortably hard” – can speak short sentences | Hard – cannot speak more than a word | | Typical duration | 1–6 minutes per rep | 30 seconds – 4 minutes per rep |

– better to finish a session feeling you could do one more rep than to be gasping for breath. That “easy but not too easy” sweet spot is where the magic happens.
