Unlike other fitness trackers that focus mainly on steps, speed, or distance, Myzone measures your effort based on your personal heart rate data. It uses a unique points system called Myzone Effort Points (MEPs) to reward the intensity of your workout, making fitness fair for everyone no matter their level. It also builds a strong sense of community by letting you join challenges and share achievements with others. With Myzone, you’re recognised for how hard you work, not just how far you move.
Founded with the vision of creating a truly inclusive fitness experience, Myzone is dedicated to connecting individuals through movement. The brand’s mission is to reward effort, not ability, making it possible for everyone, from beginners to seasoned athletes, to achieve their fitness goals. Through their innovative heart rate monitors and user-friendly app, Myzone encourages accountability, fosters a supportive community, and inspires positive, sustainable changes in lifestyle. With Myzone, you get the motivation to make fitness a part of your everyday life, achieving lasting results.
