Garmin Forerunner 620 Review

The Garmin brand is well known for its top-quality, high-performance line of Forerunner GPS watches, and this time, the company has really outdone itself with the Forerunner 620. This watch takes fitness tracking to a whole new level by including a few innovative features that are not available in previous Forerunner watches.

To find out what's new plus the pros, cons, package details, and customer ratings for this fitness watch, take a few minutes to read this Garmin Forerunner 620 review.

Measures Your Maximum Oxygen Consumption

One of the interesting features of the Forerunner 620 is its ability to measure your maximum oxygen (V02 max) consumption while your body is under aerobic load.

You can purchase the Garmin Forerunner 620 with or without a bundled Heart Rate Monitor. But whether or not you purchase the version with a Heart Rate Monitor or the one without, the Forerunner 620 will still take readings of your heart rate, running speed, and beats per minutes. This data is then used to calculate an estimation of your V02 max, which is displayed on the watch's interface.

​Also displayed is a color gauge showing how your V02 max data compares to that of other individuals of your gender and age range. Other than the displayed data, the Forerunner 620 uses your V02 max to predict your running time for several distances. You can use this information to ensure you get a good workout during your next run by attempting to cover the given distances in the predicted time.

Take note: There are two versions of the Forerunner 620 available at Amazon. One comes with a heart rate monitor and the other doesn't -- so if you don't need a HRM, you get to save some money.

Gives Accurate Data About Your Running Dynamics

Another new feature of the Forerunner 620 is the watch's in-built function that provides feedback of your running form. When paired with a heart rate monitor, the watch reports your running dynamics in 3 readings. These include:

  • Cadence – the number of strides you take every minute
  • Vertical Oscillation – the amount of bounce motion while running
  • Ground Contact Time – as the name implies, this reading will let you know how long your foot spends on the ground during each running stride

With such useful information at your fingertips, you'll be able to improve on your running form for a more effective workout. These readings are especially important for sprinters since they can give immediate feedback on performance and progress of training.

Minimizes the Risk of Injury

Resting in between workouts is extremely important and the Forerunner 620 ensures you get the right amount of rest. This watch uses your heart rate and the data collected in your previous workout to calculate how much rest time you need for your muscles to fully recover. So, with this watch, you'll be able to rest appropriately after each workout and therefore be able to perform at your best during the next workout session without risking muscle damage.
