The ideal heart rate for an individual to train depends on their age, fitness level, and current activity levels, as well as medical conditions.
To estimate your maximum heart rate depending on age, subtract your age from 220. (Source: https://www.cdc.gov/physicalactivity/basics/measuring/heartrate)
For example, the maximum age-related heart rate for a 50-year-old person would be evaluated as 220 - 50 years = 170 beats per minute (bpm). (Source: https://www.cdc.gov]
Your ideal heart rate for moderate-intensity exercise should be between 64% to 76% of your maximum heart rate. (Source: cdc.gov)
Your target heart rate for vigorous exercise should be between 77% and 93% of your maximum heart rate. (Source: cdc.gov)
Monitoring your heart rate during exercise helps you to identify any heart health issues, such as irregular heartbeats.
Understanding your target heart rate and knowing your maximum heart rate helps you to decide the intensity of your workout and monitor your heart health.
Wear a fitness tracking device, to monitor your heart rate during exercise.
