The disclosure relates generally to devices, systems and methods for measuring, transmitting, recording and displaying information relating to physical exercise and, more particularly, to a monitoring system for monitoring exercise machines comprising a lifting mechanism for selectively engaging one or more of the weights. A first aspect of the disclosure relates to an exercise machine monitoring system for monitoring exercise machines, where the exercise machines, comprise a plurality of stacked weights, the monitoring system comprises, for each of the exercise machines a repetition detector and an exercise machine identifier. The monitoring system further comprises an observer and a user device.

Exercise machine monitoring system for monitoring one or more exercise machines

A monitoring device performs a method of detecting a need for maintenance of an exercise machine comprising a time-of-flight, ToF, sensor. The method comprises obtaining a measurement signal from the ToF sensor at a predefined operating condition of the exercise machine. Based on the measurement signal, the method determines a measured distance between the ToF sensor and a reflective element in the exercise machine. The measured distance has been found to be responsive to accumulation of deposits on the ToF sensor and is thus evaluated by the method to detect a need for cleaning. The method thereby enables preventive maintenance.
