Fitness Test With Wrist-Based Heart Rate - Polar Electro IGNITE User Manual

The serenity zones are Amethyst, Sapphire and Diamond. The serenity zones tell you how well your
heartbeat and breathing are in sync and how close you are to the optimal breathing rate of six breaths per
minute. The higher the zone, the better the synchronization with the optimal rhythm. For the highest serenity
zone, Diamond, you need to sustain a slow target rhythm of around six breaths per minute, or slower. The
more time you spend in the higher zones, the more benefits you can expect to feel in the long-term.​
