"The Imperfect Measure: Importance of Regularly Elevating Your Heart Rate for Fitness"

While heart rate zone training has gained popularity, it may not be a perfect measure of exercise intensity due to individual variations and external factors affecting heart rate. The American College of Sports Medicine recommends a minimum of 150 minutes per week of moderate aerobic exercise or 75 minutes per week of high-intensity exercise for cardiovascular health. Both moderate- and high-intensity exercise offer similar health benefits, so choosing an intensity level that suits personal preference and adherence to a consistent routine is key.
