When interval training, for precise heart rate monitoring, chest straps like the Polar H10 are superior to wrist activity monitors. Use it on Strava or your smartwatch app.

A solid smartwatch cardio performance setup enables you not only to train but also to train smarter, data- and recovery-driven.
Among the most underestimated advantages of tracking cardio using wearables and apps is the encouragement they generate. Seeing your speed improve, your heart rate stabilize, or your distance go up can be strongly motivational.
Visual badges, weekly reviews, or progress charts are standard rewards that apps provide. These virtual "prizes" might encourage you to be regular, particularly when bodily improvements are not immediately visible.
Wearables also remind you if you've been inactive for too long, or to take a break, and assist you in developing healthy habits and preventing burnout.
It is only a few easy steps to get the most out of your cardio tracking devices:
Whatever mix you find works for you, most importantly, be consistent with your device and app. Progress comes with time and patience.
With all these great wearables and fitness-tracking apps, you're no longer bound to question whether your exercise is doing you any good. You can observe your improvement in real time, dissect your work, and optimize your training smartly.
It doesn't have to be the top-shelf Garmin with Strava, an Apple Watch with Fitness+, or even just a humble Fitbit with its own app – the secret lies in finding a combination that suits your lifestyle.
