Systems and methods for facilitating exercise monitoring are provided. A representative method includes: using a processor, having processor circuitry, to: compute an orientation change of the single wearable device based on the motion readings； determine a current training type and a target status associated with the current training type based on the schedule of training types； select one of the computing models associated with the current training type； compare the set of matching orientation changes corresponding to the current training type and the orientation change of the single wearable device with respect to a determination threshold corresponding to the current training type until the target status associated with the current training type has been attained； and compute an exercise amount associated with the current training type based on the target status attained.
