Heart Rate Variability

The discussion delves into heart rate variability (HRV) and its potential role in tailoring workouts. While Justin shares his experiences with HRV in athlete training, he emphasizes that personal observations and external factors like sleep and nutrition are equally, if not more, important. Sal explains that HRV reflects the state of the autonomic nervous system, suggesting it could indicate optimal training days. Overall, the value of HRV as a training metric remains a topic of exploration.
