Exercise Physiologist: The Most Accurate Way to Find Zone 2 | Better Than Heart Rate

<p>Anar Larsson from Tymewear explains why heart rate, pace, power, and even lactate can mislead runners when trying to find their real physiological Zone 2. They often end up training in Zone 3 instead. We talk about VT1, VT2, ventilation, fat oxidation, durability, and why many endurance athletes accidentally train too hard even when they think they are doing easy aerobic training. </p><p><br /></p><p>🫁 Save $100 on Tymewear Pro Training Membership</p><p>Code: E-LABTW26</p><p>👉 https://www.tymewear.com/E-LABTW26</p><p><br /></p><p>🫁 10% off Isocapnic BWB DeviceCode: JusmanSo </p><p>👉 <a href="https://shop.isocapnic.com/?sca_ref=10462834.lsRLwaoT7WUNdYI" target="_blank" rel="ugc noopener noreferrer">https://shop.isocapnic.com?sca_ref=10462834.lsRLwaoT7WUNdYI</a></p><p><br /></p><p>🏃 5K, 10K, Half &amp; Full Marathon Training Plans</p><p>👉 https://theendurancelab.run/training-plans</p><p><br /></p><p>🎓 Exclusive Discounts &amp; Resources👉 https://theendurancelab.run/exclusive-discounts</p><p><br /></p><p>In this episode:</p><p>• Why many runners are not really in Zone 2</p><p>• Why heart rate can drift without your physiology changing</p><p>• Why ventilation may be a better marker of intensity</p><p>• How VT1 and VT2 define your real training zones</p><p>• Why fat oxidation matters for endurance performance</p><p>• How to improve durability and delay fatigue</p><p>• Why breathing muscles can be trained</p><p>• How Tymewear Vital Pro measures ventilation in real time</p><p><br /></p><p>Connect with The Endurance Lab:</p><p>📩 Email: jusman@theendurancelab.run</p><p><br /></p><p>Chapters:</p><p>00:00 Are You Really Zone 2?</p><p>03:00 What Zone 2 Means</p><p>06:02 Ventilation vs Lactate</p><p>10:32 Why Heart Rate Misleads</p><p>15:20 Measuring Physiological State</p><p>22:25 Why Generic Zones Fail</p><p>26:25 Power Needs Physiology</p><p>29:11 Zone 3 Stagnation</p><p>30:17 Anar’s Background</p><p>34:00 Ventilation as Ground Truth</p><p>37:39 Ventilation vs Heart Rate</p><p>39:41 How Tymewear Measures Breathing</p><p>45:26 Finding VT1 and VT2</p><p>50:59 Where Ventilation Fails</p><p>56:04 Breathing Rate vs Tidal Volume</p><p>58:36 Tymewear Vital Pro</p><p>1:03:57 Training in Heat</p><p>1:07:49 What Is Durability?</p><p>1:11:28 Other Real-Time Tools</p><p>1:13:48 Stress and Breathing</p><p>1:14:54 Training Breathing Muscles</p><p>1:17:13 ISOCapnic BWB</p><p><br /></p><p>#runningover40 #marathontraining #zonetwotraining #heartratetraining #endurancetraining </p>
