Suunto M2, M1 manual

Zone training is an established training method, and the pre-set defaults are as follows:

●Zone 1 (60-70%): fitness zone; improves basic fitness and is suitable for weight control.

●Zone 2 (70-80%): aerobic zone; improves aerobic fitness and is suitable for endurance training.

●Zone 3 (80-90%): threshold zone; improves aerobic and anaerobic capacity and is suitable for improving peak performance.

TIP: Use zones 2 and 3 to reach a good fitness level. Avoid exercising in zone 3 too often to avoid overtraining or injury.

TIP: If you press to see the heart rate zone you are in during exercise, you will also hear a sound when your HR zone changes.

NOTE: The zone defaults follow the guidelines of the American College for Sports Medicine for exercise prescription.
