Abstract: Predicting and counting repetitions of a physical activity includes capturing first sensor data, by a first magnetometer on a wearable device, a change in a magnetic field indicative of a ferromagnetic object moving in relation to the wearable device. One or more characteristics of a user motion are determined based on the first sensor data. A count of repetitions of the user motion are determined based on the one or more characteristics of the user motion, and a notification of the count of repetitions is generated.
