HRV Training Explained: How to Know When to Push or Rest
Heart rate variability (HRV) is transforming how endurance athletes approach training by providing real-time insight into recovery and readiness. Instead of following rigid training plans, HRV allows athletes to adapt workouts based on their nervous system state, leading to better performance gains and reduced risk of overtraining. This episode breaks down what HRV actually measures, how it reflects the balance between stress and recovery, and why factors like sleep, stress, and lifestyle play a major role. The discussion also explores practical strategies to improve HRV, when to adjust training intensity, and how to interpret low HRV without overreacting. Key Takeaways HRV measures the variation between heartbeats and reflects nervous system balance Higher HRV generally indicates better recovery and readiness to train HRV-guided training leads to better performance gains than static plans Poor sleep is one of the biggest drivers of low HRV One low HRV day → switch to aerobic training Two consecutive low HRV days → consider full rest Chronic low HRV requires looking at the bigger picture (stress, hormones, lifestyle) Aerobic training is the most effective way to improve HRV Strength training is beneficial but should avoid training to exhaustion Consistency and context matter more than single HRV readings Why Your HRV Won’t Improve — Daily Reset to Boost Recovery Paul Warloski - Simple Endurance Coaching Marjaana Rakai | Nordic Performance Lab
