Yes... use this "formula"
220-your age = predicted maximum heart rate
True
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
220 - age gives you your target heart rate.
