1. A system for interfacing to an exercise machine of the type that has support feet and a resistance setting, the system comprising:
a sensor configured to be placed under a support foot of the exercise machine and configured to output a sensor signal on the basis of forces on the sensor;
a processing device configured to receive the sensor signal and comprising a memory device, the memory device storing a program code that when executed by the processing device, causes the processing device to perform operations, wherein the program code comprises
an exercise machine physics model program code comprising information about a mathematical relationship between forces on the support foot of the exercise machine and power-output values and/or the resistance setting,
and wherein the program code further comprises a sensor processing program code configured to receive the sensor signal, to output the sensor signal to the exercise machine physics model program code, and to output a workout-intensity signal comprising a measurement related to workout intensity of exercise on the exercise machine on the basis of the sensor signal and the exercise machine physics model;
wherein the processing device further comprises an output interface configured to output an output signal on the basis of the workout-intensity signal.
