The target heart rate training zone for the HRmax method is determined by calculating a percentage of an individual's maximal heart rate (HRmax). This method typically suggests training within a range of 55% to 90% of HRmax for effective cardiovascular conditioning and improvement in aerobic capacity.

Training at 55% to 90% of HRmax allows individuals to engage in moderate to vigorous intensity exercise. At the lower end of this range, 55% is sufficient to initiate improvements in fitness for de-conditioned individuals, while the upper limit of 90% provides a challenge that can enhance performance and endurance for well-trained athletes. This zone supports various fitness goals, including weight loss, cardiovascular health, and improved athletic performance.

The other ranges provided in the options do not align with the recommendations for effective training at a significant intensity level needed for these physiological adaptations. For example, lower percentages do not offer enough intensity for substantial cardiovascular improvements, and the very high percentages may not be sustainable for most individuals unless they are elite athletes.
