Garmin Forerunner 225 Review

If running is a major part of your fitness regimen, you should consider investing in the Garmin Forerunner 225 heart rate monitoring wristwatch. Featuring a round face, easy to access side buttons, soft silicon strap, and a colorful graphic interface, the Forerunner 225 shows your heart rate zone and beats per minute as you exercise.

​With this watch, you'll be able to monitor your heart rate to avoid over training and under training, as well as get access to useful information that will help you reach your fitness goals faster.

Let's take a closer look at some of the Garmin Forerunner 225's best features as well as some of its cons.​

Activity Tracking Function

With the Forerunner 225, you get more than just a simple display of your workout data. The watch features an activity tracking function that counts the steps taken, calories burned, and distance covered throughout the day when activated. The watch even gives a vibration alert that reminds you to move if you've been inactive for too long.

Built-In Sensor to Detect Pulsing Volume

Featuring one of the best technologies in heart rate monitoring, the Forerunner 225 provides continuous and highly accurate readings that you can trust.

The watch utilizes the latest version of the Mio Optical Heart Rate sensor (OHR) and LEDs, which are fitted at the back of the watch.​ ​

The LEDs shine light into the skin and the electro optical cell of the watch uses this light to detect the pulsing volume of blood flow and the user's heart rate.

To ensure the accuracy of the watch remains intact, a flexible silicone ring/seal is fitted at the back. This little seal reduces the amount of external light getting under the watch, thus maintaining the watch's accuracy since light is the archenemy of OHR sensors.

In addition to displaying workout information when you're running outdoors, the Forerunner 225 also provides data when you're running indoors. It has in-built accelerometer to support this function.

The accelerometer outputs workout data such as running pace and distance covered, much like the feedback you would get when using an indoor treadmill.

The best part is that with the accelerometer, you won't need an add-on foot pod accessory.

Graphic Interface

Through its graphic interface, the Forerunner 225 enables you to train more effectively and efficiently, and therefore reach your fitness goals a whole lot faster. This interface uses simple color graphics to display your heart rate zone. The gray color indicates that you're in your warm-up zone. Additionally, blue indicates your easy zone, green your aerobic zone, orange your threshold zone, and red your maximum zone.

Generally, reaching the first 3 zones shouldn't require much effort. However, the 4th zone requires some conscious effort. The 5th zone is the most stressful of all the heart rate zones and is a powerful fitness booster. Maintaining this zone even for a short time can deliver some amazing results. Having this information at the back of your head and knowing your heart rate zone as you exercise can enable you to get the most out of all your workouts.​
