What heart rate percentage range corresponds to HR zone one?

The correct heart rate percentage range for HR zone one is 50-64% of HR maximum. This zone is often considered the light intensity zone, where exercise is performed at a comfortable pace that can typically be sustained for longer durations. It is primarily used for warm-ups, cool-downs, and recovery workouts. In this range, individuals can primarily use fat as a fuel source, support basic cardiovascular health, and enhance overall fitness without excessive fatigue.

In HR zone one, the body is capable of efficiently utilizing oxygen, which helps in improving general conditioning and endurance levels. By working within this heart rate range, individuals are also more likely to engage in activities that support fat oxidation and promote recovery after more intense workouts. This is particularly important when designing exercise programs for women who may be focusing on both weight management and overall fitness.

The other options correspond to higher intensity levels: zones that focus on increasing cardiovascular fitness and performance but may not be suitable for those looking to begin a fitness regimen or recover from intense workouts.
