Listen to your heart. This is not just a song title, but also an important piece of advice when it comes to your triathlon training. In this episode, host Andrew Harley interviews TriDot Coach and exercise physiologist, Jeff Raines, and coach and biomedical sciences expert, Ryan Tibball. While measuring your heart rate may not be the hottest new trend in training or technology, there are so many aspects of understanding this metric that are important for training and racing. Jeff and Ryan break down heart rate training zones, decoupling, and different devices for measuring heart rates. They also discuss heart rate variability and its uses.
