trainingzone
Training zone, in exercise physiology and coaching, refers to a range of exercise intensities used to structure workouts and monitor athlete development. Zones can be defined by physiological markers such as heart rate, power output, pace, or perceived effort, and may be used individually or in combinations.
Heart rate-based zones: A common framework defines five or more zones linked to percent of maximum heart
Power-based zones: Many endurance athletes train using power data from cycling or running with a benchmark
Pace-based or subjective zones: In some training approaches, pace, pace-to-effort, or rating of perceived exertion (RPE)
Usage and limitations: The zone approach helps structure training load, balance stress and recovery, and guide
