What tool is used in the Tread Block on a 2G template to coach interval work?

The tool that is primarily utilized in the Tread Block on a 2G template to coach interval work is heart rate zones. This is because coaching in intervals relies heavily on guiding participants to reach and engage specific heart rate zones throughout the workout. By employing heart rate zones, coaches can help participants adjust their intensity to maximize benefits such as improved cardiovascular fitness and calorie burn, ensuring that individuals are working within their optimal thresholds for different phases of the workout.

Heart rate training also enables more personalized coaching, as it allows individuals to gauge their exertion levels based on their physiological responses rather than just perceived effort. This data-driven approach helps participants understand their performance and strive for improvements in endurance and strength during interval sessions.

While other tools like treadmill settings, interval timers, and performance boards can enhance the workout experience and provide structure, heart rate zones are specifically crucial for guiding interval work by monitoring and adjusting intensity based on real-time feedback.
