MEPs is an acronym for MYZONE Effort Points, and it's the metric by which everything is measured in the MYZONE system. MEPs are earned by exercising in your desired heart rate zone over a period of time. The more effort you put into your workouts, the more MEPs you earn! Knowing your tile is the first step to seeing your effort rewarded. When looking at your live tile, you can find your current MEP count in the bottom right corner.
