Your wearable tech is keeping tabs on your heart rate 24/7. Now use those digits to level up your fitness.
If you’ve sat out the whole idea of heart rate training since the days of the sweaty chest strap, reconsider plugging in – it’s easier than ever and incredibly inspiring. Besides helping you know you’ve nailed a workout, taking that data to the gym can increase your motivation and calorie burn. That’s why clubs like Orangetheory Fitness have made heart rate training a staple in their classes. A ton of activity trackers (see the latest wrist versions, next page) are already monitoring your heartbeats per minute (bpm) – valuable info, both at rest and play.
To heed your heart, glance at that bpm number – or check your pulse – ﬁrst thing in the a.m. “Resting heart rate is a great predictor of ﬁtness level. As you get ﬁtter, it drops, since a stronger heart pumps more efficiently,” says Scott McLean, the director of Human Innovation Research for Fitbit. (A resting heart rate of 60 to 100 bpm is normal; an athlete’s may be at 40.) In fact, data from more than a million Fitbit users show an extra 15 to 20 minutes of activity is associated with a lower resting heart rate.
Tracking your bpm during workouts is especially game-changing. “The talk test and RPE [rate of perceived exertion] are low-tech guides, but heart rate will give you more concrete, objective data about where you are in terms of intensity,” says David Wing, an exercise physiologist at the University of California San Diego. Plus, noting how quickly your heart rate declines after intervals is another way to track ﬁtness gains.
Ready to see how a few digits can really drive your workout? We’ve mapped out how to use the key heart rate zones to focus your routine (“Go by the Numbers,” next page). Pick a lane, and get your heart pumping.

These training zones are percentages of your max heart rate. Most bpm trackers tally each for you.
This range encompasses what is known as the fat-burning zone. But if you really want to burn fat and lose weight, working out harder will torch more total calories – and ultimately more fat – in less time.
Conditioning or endurance zone
“You’re creating the ability to use more oxygen here,” David says. If you want to train yourself to run longer, get comfy at this moderate to moderately hard intensity.
Exercising in this vigorous intensity range trains you to go harder for longer.
Do brief spurts of 10 to 60 seconds here, alternating with an easy pace, in the Conditioning or Active Recovery zone, David suggests. Build up to do HIIT one or more days a week.
