Finding your starting value for maximum heart rate

To find a starting value to find your maximum heart rate, Activio uses a a formula based on your age: 226 – age = maximum heart rate. For example, if you are 25 years of age your maximum heart rate is approximately 226-25=201 beats/minute. This starting value will be used as the basis for finding a more accurate value.

Statistically, the formula will produce a maximum heart rate value which is accurate enough for effective heart rate training. But since maximum heart rate varies within the population, some users will need to adjust this value.

Finding a more accurate maximum heart rate

1. Strap on the chest belt and start exercising
2. Check your heart rate on the Activio meter
3. Estimate your perceived level of excertion, from white to red
4. Is the meter showing too low compared to how you feel?
   Begin by lowering the starting value by 5 beats.
5. Is the meter showing too high compared to how you feel?
   Begin by raising the starting value by 5 beats.

Repeat the routine for a few classes and the system will soon be calibrated with your accurate maximum heart rate.
