Zero to 5K is a running program designed specifically for beginners. With a total duration of 9 weeks, the program consists of 3 activities per week, alternating between running and walking. As you progress through the program, the running intervals increase while the walking intervals decrease, ultimately preparing you to run a full 5 kilometers.

The app provides step-by-step guidance for each stage, indicating when and for how long you should run or walk. Even when using the app in the background, you will receive notifications with sound, ensuring you stay on track during your outdoor runs.

One notable feature of Zero to 5K is the heart rate training option, which allows you to run within an optimal heart rate range. By using your heart rate readings (in beats per minute) during your workouts, the app will notify you when you reach your minimum and maximum heart rate, signaling when to start running or walking.

Calculating your optimal effort range is made simple in Zero to 5K. Based on your age, the app estimates your maximum heart rate as 220 minus your age. Your optimal effort range is then set between 75% and 90% of your maximum heart rate. Additionally, you have the flexibility to manually adjust your desired minimum and maximum heart rate.

Whether you are new to running or looking to improve your fitness level, Zero to 5K provides an effective and user-friendly program to help you achieve your running goals.
