My husband and I are sticklers for tracking our sleep, calories, performance, recovery, and, my personal favorite, HRV status. The Garmin Forerunner 255S is a favorite among our gym friends for tracking health features. It sports a slim design and the full-color display is easy to read even in direct sunlight. The wearable is available in two sizes: 46 mm and 41 mm. Plus, with up to 12 days of battery life in smartwatch mode and up to 26 hours in GPS mode, you can keep track of your sleep and training for a while. The coolest feature on this smartwatch is a morning report that summarizes your sleep and HRV status while also providing daily workout suggestions based on your metrics the day before. This smartwatch can prepare you for your next marathon or any major race.

Also: The best sports watches you can buy Outside of a few criticisms, the Garmin Forerunner 255S is a great wearable for tracking important health metrics. It can meet your fitness needs, such as sleep, steps, stress, and how your body recovers after a full day. This device is one of the best for activities such as running, water sports, golf, cycling, and swimming, but not so much for weightlifting or more intense movements. How I rated this deal The Garmin Forerunner 255S has been around since 2022, and it is still a solid smartwatch to this day, even with all the fierce competition on the market. It's a smartwatch that delivers deep insight into your health while also being well-priced. Because of the discount, ZDNET's rating system grants this promotion a 4/5. It's a great entry point for people looking to get into fitness tech. Looking for the next best product? Get expert reviews and editor favorites with ZDNET Recommends.
