The CDC gives exercise guidelines

To that end, this article will look at a variety of different ways you can get your workout, from low-intensity to high intensity

Monitoring and Tracking

Ok, so what exactly is a moderate-intensity workout? According to the CDC that’s when your heart rate is at 64%-76% of your maximum heart rate. To get your maximum heart rate, you subtract your age from 220 – so if you’re 40, you do 220-40 = 180bpm, and that’s your maximum heart rate.

As for tracking, there are two ways to go about it: Using a heart rate monitor (HRM) which tends to be more accurate, or a fitness tracker, which is a bit less accurate but has a bunch of other features.

For HRMs, the POLAR H9 Heart Rate Sensor is a great entry-level one, and Polar is one of the most respected companies in heart rate monitoring. Since the H9 goes around the chest and can be uncomfortable for some, the POLAR Verity Sense Optical Heart Rate Sensor is an armband HRM and should be more comfortable.

I’d also suggest looking at the Scosche Rhythm24, which is more of a mid-tier option.

As for fitness trackers, my personal favorite is the Wahoo Fitness TICKR FIT since it’s so unique and doesn’t have a screen to distract you, and allows you to focus on the exercise. That being said, if you do enjoy having a screen, the Wyze Band is an excellent budget fitness tracker.

Of course, if you have an Apple device, then you already have a great fitness tracker in the form of the New Apple Watch Series 6, which I’d definitely recommend for the ecosystem. Oh, and since Apple bought Fitbit, the Fitbit Versa 3 is a cheap Apple alternative.
