Frequently Asked Questions

Why should I use a heart rate monitor?

A heart rate monitor helps you monitor your heart rate pattern, which is a big indicator of overall health. By wearing a heart rate monitor, you can see how much you’re exerting during a workout, which can then in turn help you determine if you’re pushing your body too hard or not enough. If you want to get more serious about working out and understanding what your body needs, this is a great tool to use.

What are the different types of heart rate monitors, and which one would be best for me?

Heart rate monitors fall into two broad categories: those that you wear around your wrist, and those that you strap to your chest. The latter tends to provide the most accurate results, but it can be a little tricky to get into the habit of putting it on and getting used to wearing it while you work out. Wrist-based heart rate monitors, on the other hand, are a tad less accurate, but definitely more comfortable to wear.
