Methods for profiling exercise sessions are described. An example method of determining cadence of a user disclosed herein includes receiving output signals from a sensor generated in response to consecutive footfalls of the user impacting a deck of a treadmill during an exercise session and processing the output signals from the sensor to determine respective magnitude values of a peak or a trough value of each of the output signals. The method includes detecting whether a first output signal has a first peak or trough value and detecting whether a second output signal has a second peak or trough value, determining a time interval between the first peak or trough value detected and the second peak or trough value detected, and calculating a cadence value of the user based on the time intervals.
