CNN Underscored is constantly testing products — be it coffee makers or office chairs — to find the absolute best in each respective category.
Our testing process is rigorous, consisting of hours of research (consulting experts, reading editorial reviews and perusing user ratings) to find the top products in each category. Once we settle on a testing pool, we spend weeks — if not months — testing and retesting each product multiple times in real-world settings. All this in an effort to settle on the absolute best products.
This year, we tested dozens of workout-related products — from fitness trackers to smart exercise bikes — to find the best products you need to make the most of your workouts.
Though both Fitbit models we tried excelled during our testing, the Inspire 2 was slimmer and less complicated to both set up and understand than the Fitbit Charge 4. Its sleek build ensured it didn’t catch on clothing (or anything else) while working out, and the thin screen seemed less prone to bumps and scratches, so in a way it felt less shatterproof than others. You can also set up step goals (we aimed for 10,000, for instance) as well as weight loss, water intake, wellness, sleep and more. When you log in to your Fitbit app, your home page automatically displays a semicompleted circle of how many steps you’ve taken for the day. A quick scroll will show you active minutes (when your heart rate was raised), your average resting heart rate and additional data. You can also set and log your water goals.

The Apple Watch Series 7 is the best smartwatch for Apple users — and the best smartwatch that we’ve tested. With a larger display that makes it easy to view and interact with information — from activity to heart rate and blood oxygen levels to texts — on your wrist.
You can track many workouts like cycling, dance, meditation, running, hiking, elliptical and even boxing. On your wrist, in real time, are the calories burned, length of workout and heart rate. The watch tracks this data and syncs with your connected iPhone to safely store the data.
The Apple Watch can also alert you of an increased heart rate, along with the ability to take an electrocardiogram (ECG), using both the optical heart rate monitor and an electrical sensor built into the backside of the watch and the Digital Crown. The Series 7 can also monitor blood oxygen levels and noise levels for hearing health, detect a fall and track your sleep.
Best Android smartwatch: Galaxy Watch 4 (starting at $129.99, originally $249.99; samsung.com)
The watch’s new 4-in-1 BioActive Sensor gives you more complete health and fitness monitoring, with heart rate, AFib monitoring, Vo2 levels (blood oxygen), electrocardiogram (ECG) and measure body composition. These more complex measurements are alongside steps taken, calories burned and active minutes. The Watch 4 can still automatically identify
