The percentages recommended in this course to determine your Target Heart Rate Range are _________.

The recommended percentages to determine your Target Heart Rate Range are indeed 50-85%. This range is established based on the principle that to achieve cardiovascular benefits during exercise, individuals should aim to work within a certain intensity level.

The lower limit of 50% ensures that even those who are new to exercise or have lower fitness levels can still engage in physical activity at a safe intensity that promotes heart health and endurance without overexertion. The upper limit of 85% is based on the idea that as fitness increases, individuals can safely exert themselves more, pushing towards the higher end of their target heart rate to maximize cardiovascular conditioning while still remaining within a safe range.

This focus on a 50-85% range allows individuals to tailor their exercise intensity according to personal fitness levels, ultimately helping maintain a healthy heart and improve overall fitness over time.
