Yes... use this "formula"
220-your age = predicted maximum heart rate
For a woman take the #226 and subtract your age. then figure 80% of that for an aerobic target heart rate. subtracting your age from the #226 gives your maximun heart rate when training your target heart rate will depend on what your work out goal is.
220-your age=target heart rate (i think)
(220 + your age) ×.55 = beats per minute
age
Subtracting your age when finding your target heart rate helps determine your maximum heart rate, which is crucial for safe and effective exercise. The formula typically used is 220 minus your age, providing a rough estimate of the highest number of beats your heart can handle during intense activity. This maximum heart rate is then used to calculate target heart rate zones, ensuring you train within a range that promotes cardiovascular fitness while minimizing the risk of overexertion.
220 - age gives you your target heart rate.
