Abstract
Methods for profiling exercise sessions are described. An example method for profiling an exercise session includes receiving physical characteristics or workout parameters via an input interface, generating output signals proportional to a magnitude of vertical forces imparted to the exercise machine by a user during the exercise session, and processing the output signals via a control system to determine the magnitude of peak or trough values of the output signals to profile the exercise session.
