A resistance training machine comprises a carriage with a handle coupled to move along a linear guide such as a post. First and second end portions of a flexible element are respectively coupled the carriage. A portion of the flexible element forms a loop defined by a series of guiding elements such as pulleys. The loop is coupled to a resistance element such as a weight. First and second fasteners are respectively provided in the first and second end portions of the flexible element. A user can adjust the carriage to a starting position at their desired height and affix one of the fasteners to an anchor point of the receivers. The user can move the carriage either through causing the loop of the flexible element to be reduced in length and to pull on the resistance element or plates on plate horns to perform resistance training.

Sensor data is collected from a sensor monitoring a tension generating device of an exercise machine. The sensor data is analyzed to determine whether the sensor data is within a specification. In the event the sensor data is not within the specification, an error stop mode is entered for the tension generating device.

An exercise machine includes a resistance device and vertical members extending from a base. A moveable section mounted to the vertical members moves vertically along the vertical members and horizontally towards or away from a user. Additional vertical members, which are located outside the vertical members, extend from the base, and accommodate functional training devices which facilitate three-dimensional exercise movements by the user. Each functional training device includes pulleys which accommodate a cable mechanically linked to the resistance device and extending between the pulleys to a cable termination device.

An exercise system includes a frame having a vertical post with adjustment holes extending therethrough; a lever arm attached to the vertical post via a carriage, the carriage to adjust up and down via the adjustment holes; the carriage having a brace creating a channel to engage with the post; a pivoting system extending from the brace, the pivoting system having a side to side pivoting connection attached to a second brace, the side to side pivoting connection allowing for the second brace to pivot horizontally; a rotating connection attached to the second brace via a first plate and the lever arm via a second plate, the rotating connection allowing for rotational movement of the lever arm; the carriage allows for the lever arm to be adjusted vertically, from side to side, and in a pivoting direction as needed for attachment of one or more exercise attachments.

A method of varying a dynamic resistive force during a strength training exercise includes receiving a selection of the strength training exercise from a set of available strength training exercises and obtaining exercise logic for the strength training exercise from computer memory. The exercise logic provides instructions for generating a vector that defines the dynamic resistive force provided at an end effector of a strength training apparatus during the strength training exercise. The method includes determining a real-time geometric arrangement of a plurality of cables coupled to the end effector, generating, based on the real-time geometric arrangement of the plurality of cables and the exercise logic, time-varying operating setpoints for a plurality of actuator assemblies coupled to the plurality of cables, and exerting the dynamic resistive force at the end effector by controlling the plurality of actuator assemblies in accordance with the time-varying operating setpoints.

A modular unit for physical activities, outdoors, containing a multi-purpose structural metal frame mounted on a floor of a trailer on wheels, through a fixing point. The multi-purpose structural frame includes two vertical beams linked by longitudinal and transversal longitudinal rails with sliding guides to associate two structurally extendable modules mounted at the front and rear and in turn two horizontal storage cabinets; it is also arranged in a solid way by bolts for fixing both to the multi-purpose structural frame and to the floor of the trailer to a set of individual pulley unit module and to another set of double pulley unit module associated with a weight system with protective covers, and also includes a vertical storage cabinet integrally associated with the multipurpose structural frame.

Disclosed are example embodiments of systems and methods for exercise including an exercise machine including a multiple directional force component configured to apply a multiple directional force to an exercise machine-human body interface, the multiple directional force component further configured to provide a divergent intensity to the exercise machine-human body interface to provide the human body with a resistance during a physical exercise and an artificial intelligence (AI) component configured to control the multiple directional force component.
