Music is one of the greatest motivators in any form of workout. The Forerunner 645 therefore helps streamline your devices further and includes a system that will let you store and play up to 500 songs via connecting the watch to a pair of Bluetooth wireless headphones. You can then use the watch to control your music while you’re on the move.
Heart Rate Monitor
The Forerunner 645 comes with a heart rate monitor fully integrated into the watches wrist at the back of the watch face. This is much more practical than using chest or shoulder strap with additional sensors. The Forerunner instead allows you to see your heart rate in real time all day, every day. Your heart will give you key information into your training – allowing you to ascertain whether your current training is effective, or if you’re not pushing it hard enough, or you’re overreaching.
The watch uses GPS to provide highly accurate monitoring of all your activity. The device comes with Training Status which is a new performance indicator that automatically evaluates your recent exercise history which will let you know if your training is productive, peaking or overreaching. The Training Load mode will take this one step further in evaluating your exercise volume from the last 7 days.
Using Bluetooth Smart of Ant+ you can easily connect the Forerunner 645 to your smartphone or tablet device. This allows you to access the Garmin Connect mobile app which will help you keep track of your activity over days, weeks, months and years so that you can see your progress over time and really get your teeth into the details. The app also lets you make use of Garmin’s online community of other activity track users. Once connected you can also receive your smartphone’s notifications to your watch screen including text messages, call alerts, social media notifications and more.
The Forerunner 645 comes with Garmin’s new Garmin Pay which allows you to make card payments via the watch using contactless. This makes your running trip even easier – you no longer have to carry your phone, or wallet which streamlines your running kit making your running experience easier than ever.
