For me, it's the ideal solution to add an alternative to my training that I can use both at home and on the road in hotels. The gamechanger after many years without training with bands, is certainly the ability to track my workouts through the smart STRAFFR fitness band now via app. The quality of the band is excellent, the app works flawlessly, is clearly designed, intuitive to use and the integration of the sensor in the band itself is smart, making the band very usable in training. The workouts that can be used via the app are well selected, trainers very motivating without being too pushy but helpful in getting used to training with bands again. All in all, the band helps me to do my functional training regularly to work on the muscles overall, which are often not sufficiently trained in other sports.
