Get a real aerobic heart-rate monitoring training with your Apple Watch!

Measuring with Apple Watch

MAF180 reads all Workouts data from the Apple HealthKit, including heart rate, run distance, active energy burned etc. Thanks to Apple HealthKit, with API provided by HealthKit this app get all information needed.

Your Apple Watch taps you on the wrist when heart rate exceed the high HR value. You can leave your iPhone at home when you go for training!

- High HR Warning: vibrate and color indicate
- Metronome: Beep voice to help your step frequency
- Work-route: Location saved to your workout with the help of HealthKit, so you can view route information with Fitness or other applications on your iPhone later.

A heart-rate monitor is the most important tool for developing optimal endurance and better fat-burning. This app is a valuable tool that not only guides your training but is part of an important assessment process, and can even be used in some competitive situations.

This “MAF 180 Formula” enables athletes to find the ideal maximum aerobic heart rate in which to base all aerobic training. When exceeded, this number indicates a rapid transition towards anaerobic work.

The MAF 180 Formula for determining your MAF HR

Subtract your age from 180, then modify from one of the categories below:

- If you have or are recovering from a major illness (heart disease, any operation or hospital stay, etc.), are in rehabilitation, are on any regular medication, or are in Stage 3 (chronic) overtraining (burnout), subtract an additional 10.

- If you are injured, have regressed or not improved in training (such as poor MAF Tests) or competition, get more than two colds, flu or other infections per year, have seasonal allergies or asthma, are overfat, are in Stage 1 or 2 of overtraining, or if you have been inconsistent, just starting, or just getting back into training, subtract an additional 5.

- If you have been training consistently (at least four times weekly) for up to two years without any of the problems mentioned in a) or b), no modification is necessary (use 180 minus age as your MAF HR).

- If you have been training for more than two years without any of the problems listed above, have made progress in your MAF Tests, improved competitively and are without injury, add 5.

The MAF 180 Formula may need to be further individualized for athletes over the age of 65. For some, up to 10 beats may have to be added for those only in category (d) of the Formula. This does not mean 10 should automatically be added, but that an honest self-assessment be made.
For athletes 16 years of age and under, the formula is not applicable; rather, an MAF HR of 165 has been used.
