Abstract: An exercise device with advanced bench-cycling exercises for glute, abs and leg toning, for use in both the stomach down and up positions, has: a bottom support and at least one main support stem extending upwardly; a main joint body support frame rotatably connected to the support stem to allow lower support and upper support bars to be tiltable. The upper support bar is sufficient to support at least a portion of a human torso, and is rotatably connected to the main joint; one or two lower support bars adjustable in length, and having a top portion connected to the main joint, upper support bar or the at least one support stem; and a bottom portion extended away from the main joint; two cranks located on the bottom portion of the lower support bar; and a pair of pedals separately connected to their cranks, the cranks being adjustable in length.

Abstract: An exercise device with advanced bench exercises for glute, abs and leg toning, for use in both stomach down and up positions, has: a bottom support and at least one main support stem extending upwardly; a main joint body support frame rotatably connected to the support stem to allow lower and upper support bars to be tiltable. The upper support bar sufficiently supports at least a portion of a human torso and is rotatably connected to the main joint; one or two lower support bars adjustable in length, and having a top portion connected to the main joint, upper support bar or at least one support stem; and a bottom portion extended away from the main joint. Some embodiments have near-horizontal torso support, and some have titled torso support. There are pedals for cycling, except some embodiments replace rotating pedals with fixed footrests to replace cycling with leg lifts.

Abstract: An adapter for connecting stationary portions of two housing that are connected via a rotatable shaft. The adapter includes a hollow body that extends from a first axial end to a second axial end. A first fastening feature is arranged proximate the first axial end and a second fastening feature is arranged proximate a second axial end. The hollow body has an interior area that extends from a first lateral opening that is located proximate the first axial end to a second lateral opening that is located proximate the second axial end. One or more longitudinal openings are located between the first axial end and the second axial end. The one or more longitudinal openings are configured to access the interior area.
