Fort is said to be the first wearable that can automatically and accurately track strength training, while also supporting cardio workouts as well as sleep and stress tracking. Developed by former Tesla engineers, the wristband promises a battery life of one week.

Fort is offering a new alternative to the Whoop 5.0 fitness tracker, which is designed to record strength training more precisely than any competing product. According to the manufacturer's marketing, the device can recognize over 50 different exercises without requiring manual selection. Instead of simply displaying an increased heart rate, Fort is said to show, for example, exactly how many squats, push-ups or sit-ups have been performed.
 


To record a workout, there is no need to open an app or press a button; as long as Fort is worn on the wrist, the wearable automatically records every training session. It uses data from a heart rate and motion sensor, which is analyzed using advanced algorithms. The accompanying smartphone app not only tracks repetitions of different exercises but also visualizes weekly progress and identifies under-stimulated muscle groups.

Fort also tracks cardio workouts such as running and monitors sleep and stress levels. Weighing just 30 grams, the wristband is designed for comfortable all-day wear, and the battery promises a runtime of seven days. Fort is available in silver, black or gold and can be combined with a variety of other wristbands to match your outfit.
 

Prices and availability

The Fort Fitness wristband will be available from the third quarter of 2026, but the manufacturer will initially only deliver within the USA. The wearable costs US$289. Further information can be found on the manufacturer's website.
