The Königsfeder from Body & Mind® convinced us in our practical test with its high functionality. It is an effective and reliable training device for strength training.
The flexible intensity is another advantage. The high-quality dumbbell is available in 30 kg and 50 kg and uses a carbon steel spring to provide a force that adapts to the individual effort required to achieve maximum results. This feature is particularly important for building muscle mass. The king spring trains the entire upper body.
The flexible bending dumbbells isolate and train the entire upper body, i.e. arms, neck and shoulders, triceps, biceps and chest muscles. This speaks for the good quality of the material and the careful workmanship.
The training effectiveness of the Königsfeder is excellent. The Königsfeder can be tested for 30 days without obligation. If you are not satisfied, you can return the bending barbell and get your money back immediately. The flexible resistance tones the upper body. The training is long-lasting and profound. The resistance changes depending on how much the dumbbell is bent, allowing a wide variety of exercises to be performed.
The inner deep muscles are also strengthened and built up. The flexible resistance minimizes the risk of injury.
In the practical test, the quality of the Body & Mind® king spring finally convinced us. The mobility, functionality, slip resistance, variations, intensity and training effect make the Königsfeder a recommended choice for every fitness enthusiast.
