What is the target heart rate for a 70-year-old male exercising at very light intensity?

To determine the target heart rate for a 70-year-old male exercising at very light intensity, it’s important to take into account the general heart rate guidelines used in fitness. For older adults, very light intensity is generally characterized by a heart rate that is at the lower end of the intensity spectrum.

The typical formula for estimating maximum heart rate is 220 minus the person's age. For a 70-year-old, this calculation gives a maximum heart rate of approximately 150 beats per minute.

When exercising at very light intensity, the target heart rate zone is usually about 40-50% of the maximum heart rate. This would lead to a target heart rate of around 60-75 beats per minute, as it aligns with the lower intensity exertion level appropriate for someone in this age group. Therefore, the lower range is focused on ensuring safety and allowing for light activity without overexertion.

The choice indicating a target heart rate of 80-95 beats per minute falls outside the very light intensity category, as it suggests a higher exercise effort than what is considered 'very light.' This could lead to unnecessary stress on the cardiovascular system for a 70-year-old individual.

Thus, the correct target heart rate for a
