1. An apparatus comprising:

  • a user-wearable sensor to measure a level of physical resistance in a first athletic activity and to generate sensor data indicative of the measured level of physical resistance, wherein the user-wearable sensor is an air flow sensor; and

    a controller to receive the sensor data to (1) determine a first force-to-motion ratio based on the sensor data, (2) conduct effort normalization based on (a) the first force-to-motion ratio and (b) a second force-to-motion ratio based on data from a second athletic activity, and (3) automatically generate control signals to adjust the level of physical resistance based on the effort normalization.
