Abstract: In one variation, a pulley arrangement includes a base pulley portion rotatable within a driving plane, an adjustable pulley portion coupled to the base pulley portion wherein the adjustable pulley portion is rotatable relative to the base pulley portion within the driving plane, and a driving member including an end coupled to the adjustable pulley portion wherein at least a portion of the driving member is wrapped at least partially around the adjustable pulley portion. In another variation, a pulley arrangement includes a base pulley portion rotatable around an axis, an adjustable pulley portion coupled to the base pulley portion and movable in a first direction parallel to the axis, and a sliding block engaged with the adjustable pulley portion, wherein the sliding block moves in a second direction different from the first direction, in response to compression of the adjustable pulley portion against the base pulley portion.

Abstract: The present invention provides a computerized interactive training method and system for receiving a user data including physical user data, medical history data and athletic goal data for the user. The method and system further includes determining a baseline data set for the user and generating a training routine for the user based on the baseline data set and the user data, including selecting a plurality of exercises for the user directed towards the athletic goal data. The method and system further includes determining a network of related users electronically networked via a networking interface, transmitting the training routine to the user and notifying the related users of the training routine. The method and system provides for receiving training feedback data from the user, including exercise-specific information and sharing the training feedback data with fellow community users.
