The target heart rate range for teens during aerobic exercise is typically around 145-170 beats per minute. This range is based on the understanding that teenagers have a higher maximum heart rate compared to adults, which allows for more intense aerobic activity. The target heart rate zone is essential for ensuring that exercise is effective, promoting cardiovascular fitness while minimizing the risk of overexertion.

This range corresponds to 70-85% of a teen's maximum heart rate, which is commonly calculated as 220 minus the person's age. For example, a 15-year-old would have an estimated maximum heart rate of 205 beats per minute, making the 145-170 beats per minute range an appropriate target for achieving cardiovascular benefits. Engaging in exercise within this heart rate zone allows teens to improve their endurance, strength, and overall fitness level while also supporting healthy growth and development during this critical stage of life.
