Abstract: A system for creating a personalized, dynamic, multi-sport training plan for a user comprises a question generating module; a user input module which accepts user answers to questions generated by the question generating module and accepts other inputs relating to the user; and a processing module which collects and analyzes the answers to the questions and the inputs and thereafter, based at least in part on a calculation of an exponential moving average (“EMA”) of said answers, creates a training schedule for each sport, which is dynamically linked to all previous user inputs; wherein the question generating module, by way of an intelligent link to all previous user inputs and feedback direction from the processing module, creates a plurality of further questions for the user to enable modifications to be made to training schedule for each sport.

Abstract: A heat exchanger includes a plurality of flattened, multi-channel heat exchange tubes of generally J-shape extending between an inlet header and an outlet header. Each heat exchange tube has a base bend that extends horizontally between the vertically extending relatively shorter leg, which is in fluid flow communication with the fluid chamber of the inlet header, and the vertically extending relatively longer leg, which is in fluid flow communication with the fluid chamber of the outlet header.
