According to one example, an exercise system includes a vertical housing, a first weighted touchpoint coupled to the vertical housing and configured to allow a user to exercise one or more muscles on a first side of the user, a first weight system coupled to the first weighted touchpoint, a second weighted touchpoint coupled to the vertical housing and configured to allow the user to exercise one or more muscles on a second side of the user, and a second weight system coupled to the second weighted touchpoint. The exercise system further includes a control system configured to cause the first weight system to automatically provide a first heavier weight to the first weighted touchpoint for a first exercise and further cause the second weight system to automatically provide a second lighter weight to the second weighted touchpoint for the first exercise.

The present invention provides a competitive weightlifting system capable of interacting with and comparing weightlifting performances of multiple users, and creating competition between such users by displaying a ranked list of performances by those users. The system may include a frame for supporting and guiding a lift bar, sensors mounted to the frame for measuring and refereeing the performance of a user, a controller housed in the frame for tracking and ranking user performances with an interface for creating and logging into user profiles, and a communication device for sharing user performance data with other remote competitive weightlifting systems (e.g., competitive weightlifting systems in other gyms or homes) in order to create a wide-ranging competition between, and ranked leaderboard of, the many users.

A selectable weight set apparatus includes a handle assembly including a handle having a first end portion and a second end portion opposite the first end portion. A first weight set is adapted to be supported on the first end portion of the handle and a second weight set is adapted to be supported on the second end portion of the handle. Each of the first and second weight sets includes a plurality of weight plates. An adjustment assembly selects a number of weight plates to be retained to the handle assembly. The adjustment assembly includes at least one selector for movement relative to at least one of the first and second weight sets to engage and select the weight plates in said at least one of the first and second weight sets. A locking assembly fixes the selector relative to said at least one of the first and second weight sets.

A weight training auxiliary device for adjusting a weight training load of training equipment includes a plurality of weights that generate a load, a load transmission mechanism configured to transmit the load of the weights to the training equipment, and a weight attaching/detaching mechanism configured to attach and detach the weights. At least one of the weights has an electromagnet or a permanent electromagnet built in. The weight attaching/detaching mechanism includes a conduction relay configured to control supply of power to the electromagnet or the permanent electromagnet so that the weight training load is adjusted by attaching or detaching the at least one of the weights.

A pulley weight exercise method includes the placement of a plurality of weights from an adjustable dumbbell on a base. The weights each have a centrally positioned opening vertically extending therethrough to define a receiving space. A user determines a quantity of the weights to be used during an exercise to define a selected number. The selected number of the weights is engaged to a carriage. The carriage is attached to a first end of a cable positioned on a pulley suspended from an upper end of a vertical support. The vertical support is attached to and extends upwardly from the base. Pulling a second end of the cable pulls the carriage and the secured weights upwardly toward the upper end. To perform an exercise, a handgrip is attached to the second end of the cable.

A more efficient exercise system can be facilitated by interactive components. The interactive components can communicate with mobile devices, users, server devices, weight lifting machines, etc. The interactive components can also generate exercise data and provide prompts to a user to facilitate a more efficient workout. Additionally, third-parties can receive user workout data and manipulate, or provide guidance to the user to manipulate, exercise equipment remotely to assist a user in attaining his or her goals.

A bi-directional exercise machine has a work arm, first and second cams coupled to the work arm, a resistance mechanism, and a pulley assembly that couples the resistance mechanism to the work arm via the first and second cams so that movement of the work arm is resisted by the resistance mechanism according to first and second resistance profiles provided by the first and second cams, respectfully. The pulley assembly has a primary pulley cable having a first end coupled to the first cam and a second end coupled to the second cam. When the work arm is in a rest position the first and second ends of the primary pulley cable both extend from cable tracks of the first and second cams, respectively, at a tangent, and in particular so that the resistance mechanism applies a resistance force on the work arm via the pulley assembly immediately upon movement of the work arm out of the rest position.

An exercise system for exercising a body's oblique muscle group relies upon a wheel mechanism having an outer wheel portion arranged at a first radial distance and an inner wheel portion arranged at a second radial distance, where the outer and inner wheel parts include respective sets of handgrips. A weight system is arranged to be coupled to and decoupled from the wheel mechanism. A coupling mechanism couples the weight system to and decouples the weight system from the wheel mechanism, in a first circumferential direction, or in a second circumferential direction. The hand grips allow a user to grasp the wheel mechanism and turn it in the first or the second circumferential directions against a respective force that the wheel mechanism is turned against that is defined by the aggregate selected weight when coupled to the wheel mechanism, in one of the first and second circumferential directions.

The therapeutic isometric testing and isotonic training exercise device disclosed herein may allow for isometric strength testing and isometric and isotonic strength training of a user to prevent or treat soft and connective tissue deficiencies. The device may comprise, generally, a leg press, chest press, and shrug press exercise device combination having a plurality of electronic components. The device may comprise a seat assembly and weight stack assembly connected to an articulating frame, and may further comprise a weight locking pin and a plurality of load sensors for user work measurements. A proprietary software may be integrated into the device, and each user may have a personal user account and customized training regimen designed for them based on system inputs and readings.

A cradle for supporting an adjustable free weight assembly that includes first and second weight plate sets. End walls and side walls of the cradle define a cavity sized to receive the free weight assembly. The end walls engage plate portions and locking element portions of outermost weight plates of the free weight assembly when received in the cradle. Inboard surfaces of the side walls engage portions of weight plates in at least the first weight plate set to substantially inhibit the first weight plate set from moving vertically or laterally between the side walls. The configuration of the inboard surfaces of the side walls aligns the weight plates in the first weight plate set both vertically and horizontally so that central openings in the weight plates for receiving a selector shaft are substantially concentric.
