A multitude of sensors are integrated in the intelligent handle of this dumbbell. Individual body functions such as heart rate, calorie consumption or oxygen content can thus be monitored during workout and controlled and optimised through targeted exercises – not least with the help of a suitable training app. With an easy-to-use safety holder, the four dumbbell weights are individually attached to the coated handle. All parts can be conveniently stored in a special box which also doubles as a charging station.
