Apparatus for Resistance-Based Fitness Training

An apparatus comprising:

• a mechanism having two subsections and a subsection joint, wherein the subsection joint is mechanically interposed between the two subsections;
• wherein the subsection joint further comprises a locking mechanism within the subsection joint in a locked mode and in an unlocked mode at a user selected position;
• wherein the subsection joint is mechanically interposed between the two subsections when the locking mechanism is in the locked mode and when the locking mechanism is in the unlocked mode;
• wherein when the locking mechanism is activated in the unlocked mode, the subsection joint is mechanically configured such that each of the two subsections may rotate within three-dimensional space;
• wherein when the locking mechanism is activated in the locked mode, the subsection joint mechanically prevents the two subsections from substantially deviating from their positions in three-dimensional space each of the two subsections occupied just prior to the activation of the locking mechanism to the locked mode;
• and
• wherein the activation of the locking mechanism in the locked mode and the activation of the locking mechanism in the unlocked mode occurs by a single activating action without movement of the two subsections.

An apparatus comprising:

• a joint mechanism;
• a joint casing enclosing the joint mechanism;
• a locking device that selectively engages the joint mechanism via an actuator within the joint casing in a locked mode and in an unlocked mode;
• wherein the actuator partially protrudes from the joint casing mechanically connected to the locking device;
• wherein the joint mechanism comprises at least one joint coupling connector, and wherein each of the at least one joint coupling connector is mechanically interposed with a device external to the joint casing when the joint mechanism is in the locked mode and when the joint mechanism is in the unlocked mode;
• wherein when the joint mechanism is in the unlocked mode, each of the at least one joint coupling connector mechanically allow each device external to the joint casing that is mechanically engaged with each of the at least one joint coupling connector to rotate within three-dimensional space;
• wherein when the joint mechanism is in the locked mode, each of the at least one joint coupling connector prevent each device external to the joint casing that is mechanically engaged with each of the at least one joint coupling connector from substantially deviating from the position in three-dimensional space each device external to the joint casing that is mechanically engaged with each of the at least one joint coupling connector occupied just prior to the engagement of the joint mechanism in the locked mode;
• wherein the activation of the locking mechanism in the locked mode and the activation of the locking mechanism in the unlocked mode occurs without movement of the two subsections movement of each device external to the joint casing;
• and
• wherein the locking device engages the joint mechanism via the actuator within the joint casing in the locked mode and in the unlocked mode by a single activating action without movement of each device external to the joint casing.
