Garmin's new Forerunner 225 GPS sports watch combines cutting-edge technologies to create a running watch that doubles as a life-fitness device. In addition to built-in heart rate monitoring using optical technology, it has an accelerometer that tracks your daily activity and calorie burn.

Garmin made heart rate training easier in two ways: You don't need to wear (or purchase) a heart rate monitor strap, and Garmin created a very easy-to-see and follow color-coded heart rate training zone display for the watch.

Based on the age and weight that you input during watch setup, the Forerunner 225 automatically establishes heart rate training zones including warmup, easy, aerobic, threshold, and maximum. Color coding, from gray to bright red, as well as a graphical circular display make it easy to train in your zones. You may also customize all of your heart rate zones, since some athletes naturally run above or below the generally recognized standards for age and weight.

No Need for a Foot Pod

Many of us mix indoor and outdoor workouts, and in the past getting your stats from a treadmill workout involved adding and syncing a foot pod sensor. The Garmin Forerunner 225 GPS does not need a foot pod to measure a treadmill workout, since it can draw upon the data provided by its built-in accelerometer.

How the Heart Rate Monitor Works

"To measure heart rate at the wrist the Forerunner 225 uses a built-in optical sensor that shines light into a user’s skin and measures the amount of light returned," states Garmin.

"Because there are slight changes as blood pumps through the wrist, the sensor detects those changes and uses an advanced filtering process to determine reliable and accurate heart rate. Additionally, a light seal on the back of the watch blocks out ambient light to help ensure proper heart rate detection."

Auto-Upload to Garmin Connect and Live Tracking

I'm a regular user of Garmin's Connect online fitness and training log service and have reviewed it here. It's an excellent freebie and plays very well with Garmin devices. The Forerunner 225 automatically uploads to Connect. "Just download the free Garmin Connect Mobile app to your smartphone and then pair your watch," states Garmin. "When you save your completed run, it will automatically upload when you’re in range of your phone. Additional connected features include live tracking, which allows your friends and fans to follow along and see your stats in real-time. You can also share your activities on your social media sites by posting updates through the Garmin Connect Mobile app."
