What is target heart rate zone definition

Target heart rate zone is the range of heartbeats per minute (BPM) that a person should aim to reach during aerobic exercise in order to achieve maximum cardiovascular benefits. It is typically expressed as a percentage of the individual's maximum heart rate, which can be estimated by subtracting their age from 220. Exercising within the target heart rate zone ensures that the heart is working at a level that is both effective and safe for improving cardiovascular fitness.
