The Fitbit Charge 4 is durable, simple to use and comfy for all-day wear. We’ve been using ours for months now and recommend it to anyone who wants to better understand their daily activity, steps taken and floors climbed, and to monitor their workouts - anything from cycling to yoga. In fact, the Charge 4 is designed to automatically track 20 forms of exercise, whether you’re running on a treadmill (opens in new tab) or breaking a spin-class sweat on an exercise bike (opens in new tab). The only difference between the two editions is the band: the Fitbit Charge 4 Special Edition comes with a classic wristband and a woven reflective band. And there are other Fitbits on sale too, including some of the brand’s best smartwatches (opens in new tab), the new Fitbit Sense and the beginner-friendly Fitbit Versa 2. The Charge 4 is one of the most popular Fitbits of recent years, and sits quietly on the wrist where it tracks activity, resting heart rate, and calories burned all day long. It will prompt you to move more during the day, so you aren’t so sedentary, and if you’re feeling stressed it will guide you through some relaxing breathing exercises. The Fitbit Charge 4 is good for women’s health too, as it’s designed to track a person’s menstrual cycle so that you can understand how your periods affect your energy levels, sleep quality, and mood. When you buy the tracker, you’ll also get a 90-day free trial of Fitbit’s online fitness program (opens in new tab), offering classes covering everything from body strength training and pilates, to HIIT and mindfulness - handy if you haven’t yet fired up a meditation app (opens in new tab) to enjoy the benefits of this relaxing practice.
