The Forerunner 25 is a more basic version of all its bigger brothers, with heart rate monitoring (only on some so make sure you check), an activity log of daily steps and calories burnt, as well as the ability to be synced to Garmin Connect to view workout history. It can record up to 7 workouts in its memory and has the added benefit of coming in small versus large size. Top tip: if you are after your heart rate measurements you can also purchase the HR Monitor, compatible with your watch.
