Patent attributes
An adjustable resistance training apparatus that is provided with one or more elongated elastomeric members that are supported by a carrier. The adjustable resistance training apparatus also includes a slide that is configured to be moved along a guided path in response to a force exerted by a user's body. The slide includes an engagement member that is configured to permit selective engagement to the second end of one or more of the elastomeric members, once positioned by the carrier, to cause the selected elastomeric member or members to be stretched along a second plane in response to movement of the slide along the guided path. The adjustable resistance training apparatus can be coupled to isotonic weights in the form of a selectable weight stack that moves along a second guided path in response to a force exerted by a user's body or used with plate loaded devices. The combination of resistance tubes and weights results in progressive resistance regardless of the speed of movement of the weight stack.
