What should the heart rate be during an endurance energy zone in a spin class?

During an endurance energy zone in a spin class, the heart rate is typically targeted at a range that allows participants to build stamina and improve cardiovascular fitness. This range is commonly recognized as being between 75% to 85% of an individual's maximum heart rate.

This particular heart rate zone is ideal for endurance training because it helps improve the efficiency of the cardiovascular system without pushing the body into anaerobic exercise, which occurs at higher intensities. At this level, participants can sustain activity for a longer duration, leading to improved aerobic capacity and overall endurance.

Additionally, training within this heart rate zone helps enhance fat oxidation, utilizing fat as a primary fuel source during longer workouts. This is essential for cyclists and individuals looking to increase their endurance for long rides or other prolonged physical activities.
