A member asked:

Maximum heart rate: The maximum heart rate response to exercise can be predicted using the 220 - age in years. For you at age 24 the maximum rate should be 196. To achieve maximum benefit you should aim for 50 - 85% of the maximum predicted heart rate or 98 - 166. As your fitness level increases, your resting heart rate will decrease.
