Answer:
Below
Step-by-step explanation:
Not sure what numbers you have been taught to use, but heart rates (BPM) above 80% of your maximum heart rate is anaerobic
your approximate Max heart rate = ( 220 - age in years)
so if you are 20 y/o max = 220 - 20 = 200 bpm
80% of this is 160 beats per min <===above this is anaerobic
