Abstract: In one aspect and embodiment, the present invention provides a fitness training apparatus comprising: a controller configured to communicate instructions to a load generator to apply a selectively adjustable load to at least one retractable line provided in or on a base. The retractable line has a free end region, wherein the at least one retractable line being extendible from a retracted state to an extended state upon application of a force to the free end region, wherein the load applied to the at least one retractable line acts against the force applied to the free end region. The controller is configured to perform operations comprising: setting a target speed band for the at least one retractable line; receiving a speed of the at least one retractable line; and responsive to comparing the speed of the at least one retractable line to the target speed band, modifying the selectively adjustable load to the at least one retractable line to maintain the target speed band.

Abstract: A fitness training apparatus comprising: a base, at least one retractable line provided in or on the base, and a load generator provided in or on the base for applying a selectively adjustable load to the at least one retractable line. The retractable line has a free end region for operation by a user, wherein the at least one retractable line is configured and arranged to be extended from a retracted state in or on the base to an extended state upon application of a force to the free end region of the retractable line by the user. The load applied to the retractable line by the load generator resists or acts against the force applied to the free end region by the user for extending the retractable line from the retracted state to the extended state.
