  • Patent number: 5158520
    Abstract: A resistance apparatus for use in performing squat exercises, in which a belt-type device is worn by a person for providing a resistance connection between the person's legs. The resistance apparatus includes a chain, which is connectable at one end to a connection arrangement associated with the belt-type device. The other end of the chain is connected to a stack of weights or any other satisfactory resistance-providing device, with the chain being trained around a series of pulleys. A tracking arrangement provides front-to-rear movement of the chain at a point below the connection of the chain to the belt-type device for maintaining the resistance directly below the person's center of gravity as the person moves in a front-to-rear direction during performance of a squat exercise.

  • Patent number: 4984786
    Abstract: A weight suspension apparatus for squat exercises. The apparatus comprises a belt, a front strap, a rear strap, a weight and a multi-link chain for connecting the weight to the front and rear straps. The front and rear straps are each preferably V-shaped, with the nadir of the V-shape depending between the legs of the user. The upper ends of the front and rear straps are preferably connected to the belt so that an upper end of each is located on either side of the user's body when the belt is secured thereto. The weight is attached to the straps by a multi-link chain allowing variable placement of the weight in a front-rear direction, to change the point of attachment of the weight according to location of the user's center of gravity.
