Disclosed is a track exercise device including at least two substantially parallel tracks, at least four movable platforms, wherein at least two movable platforms are on a first track, and wherein at least two movable platforms are on a second track. A transverse attachment attaches the movable platforms on adjacent tracks, a longitudinal attachment attaches the movable platforms on the same track, and a tilting adjustment provides for inclined or flat movement.

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 weightlifting machine includes a carriage support, a carriage moveably mounted on the carriage support and configured to move along the carriage support, and a locking mechanism that is moveable between a locking position, where the locking mechanism engages the carriage and supports the carriage at an elevated position above a lowermost position of the carriage, and a release position, where the locking mechanism does not engage the carriage, and the carriage is free to move below the elevated position.

A weight training apparatus using hydraulics or pneumatics for applying positive and negative resistance closer to a user's maximum capacity throughout a lift is provided. The weight training apparatus allows for weight training without weights. The weight training apparatus may provide a more effective and safer mechanism for training than conventional techniques.

A multipurpose exercise device is provided. The device includes features which allow the device to exhibit self-stabilizing features. The device includes a weighted body characterized by at least three substantially-loop-shaped handles which have dimensions and arrangements that are effective to cooperatively urge the device into one of several predetermined self-stabilizing rest positions. The rest positions are characterized by engagement portions of two of the provided handles resting against a support surface, while an elongated device bore extending along a center axis of the device is maintained in a substantially-horizontal orientation. The device may be stored safely in a variety of arrangements, including on a rack typically used for dumbbell storage.

A resistance device includes a first rotating assembly having a first rotating member, and a second rotating assembly having a second rotating member and a plurality of magnets. A transmission unit is connected to one of the rotating assemblies for driving rotation of the same. A drive unit is connected to the other one of the rotating assemblies, is configured to receive a control signal, and is configured to drive rotation of the other one of the rotating assemblies according to the received control signal. Eddy currents generated by the first rotating member provide resistance to the transmission unit. A resistance training machine having the resistance device is also disclosed.

A squat bicycle provides a squat bicycle in which a power transmission means and a frame are driven in a linked manner. The frame is configured to include a top tube, a down tube, a seat stay, and a chain stay. The front end of the top tube is hinge-coupled to the down tube, and the rear end is hinge-coupled to the seat stay. The seat stay is divided into a first member in which the front end is hinge-coupled to the top tube and a second member in which the rear end is hinge-coupled to the rear end of the chain stay, and a rear end of the first member is hinge-coupled to a front end of the second member.

The present invention relates to a stand for a hexagonal bar or a trap bar for weights or the combination of a stand and a hexagonal bar or a trap bar. The stand has an opening for user to enter and is enclosed on all other sides. The stand is preferably approximately 9 inches high above the ground on which it rests so that a hexagonal bar or trap bar having weight plates will be off the floor of the ground when resting on the surface areas of the stand thereby facilitating the removal and replacement of the weight plate without the need to lift the bar upward from the ground. The stand permits a user to work in the area of the stand if preferred.

The invention relates to a machine for sports training, which comprises a frame pivotably connected to a lever actuated by a user's arms, the at least one lever being connected to two main coupling elements situated parallel to each other, such that when the elements move, they describe an identical path at the same time, transmitting the movement of the at least one lever to resistance means. The machine provides continuous resistance to the actuation of the lever by the user, and a moment of inertia that prevents stops and jerks at the end of the stroke of the lever. The machine is provided with means for supporting the user, such as a platform, solidly fixed to the frame such that while the user trains the upper body, he or she can also train the lower body, at will, by performing exercises on the platform.

Disclosed herein are devices, systems and methods for redistributing the normal weight distribution of a user in a standing position. One example is a postural platform for either the left or right foot having a bottom surface defining a reference plane, a top surface configured as a foot contact surface and a perimeter side wall between the bottom and top surfaces. The top surface of the postural platform is rotated about a first rotational axis parallel to the reference plane and rotated about a second rotational axis orthogonal to the reference plane. In another example, a system includes first and second postural platforms that are independent of one another. In other example, the device is a sandal, shoe, sneaker or any foot covering with a tops surface being at a complex angle to a bottom surface. The top surface is tiled downwardly either to the left or right and turned either counter-clockwise or clockwise based on whether it is a respective left or right postural platform.
