Abstract: A multi-purpose, adjustable fitness apparatus is provided for performing exercises; in particular, sliding pull-ups and push-ups. Two in-line metal bars are interposed by a T-connector. A sliding handle grip may be disposed on each bar between a pair of retaining collars. A radius elbow including a foot is attached to each bar. A first adapter for a first setting includes a crossbar and elbow tube is slidably locked to the perpendicular leg of the T-connector. The apparatus may be mounted over a doorframe; the elbow tube and T-connector provides adjustability to fit frames of various widths. A second adapter for a second setting includes a third foot fitted to the T-connector, and provides stability on a horizontal surface.

Abstract: Devices, apparatuses, systems and/or methods related to weight plates. Specifically, the disclosed devices, apparatuses, systems and/or methods relate to nested weight plates including a first weight plate increment and a second weight plate increment configured to receive the first weight plate increment. The nested weight plates may include a turning mechanism including a turning circle and/or a screw. The screw may be received by the first weight plate increment such that rotation of the turning circle engages and/or disengages the second weight plate increment. In this manner, a user may select to total weight desired.

Abstract: An exercise device for performing push ups and pull ups is disclosed. The device contains first and second tubes slidably engaged with a handle, which may be covered by a grip. A spring biases to the two tubes, drawing them inwardly together with respect to the handle. A first foot tube, including a first base, engages the second end of the first tube; a first button connector arranged to selectively lock the first foot tube with respect to the second end of the first tube. A second foot tube, including a second base, engages the second end of the second tube; and a second button connector selectively locks the second foot tube with respect to the second end of the second tube. The device may be engaged with a door frame to perform pull-ups.

Abstract: A stability bar system is disclosed for use in exercising and muscle toning. The system provides an unstable base to engage core muscles while performing exercises. The bar has a central attachment point, and multiple off-center attachment points on which to attach resistance tubing, bands, cables, or straps. The body of the bar is made from rigid plastic or metal, and allows for diverse exercises by providing interchangeable attachments, and multiple configurations, to vary stability and resistance. The bar may also be used to perform body weight exercises. The stability bar system is designed to allow an exerciser to engage core muscles while focusing on other, primary muscles.

Abstract: A step apparatus is disclosed for individual training or group fitness classes. The step apparatus may simultaneously contain a plurality of step heights for a dynamic work out. The platform heights may be quickly adjusted to user preference. The adjustable settings may be self-contained within a single unit, or alternate pieces may be provided for additional variation. The step apparatus has a frame and a plurality of step platform units, with each platform unit having two height settings.

Abstract: A shoe is disclosed for use in playing soccer or other activities. The shoe is designed to offer greater power and protection for a wearer's foot and ankle. The shoe is formed with a flexible outsole and an adjusted straight last. The upper is designed with a wide toebox and short lacing system. The shoe uses a unique cleat system. These features decrease the chances of injury and also give a player, such as a soccer player, enhanced ball control and power. This shoe can be modified for use, for example as a running shoe, or a casual shoe.

Abstract: Folding hurdles are disclosed. Some example folding hurdles may include a generally horizontal bar. A first leg may be pivotably coupled to a first end of the generally horizontal bar. The first leg may include a generally horizontally extending first foot and/or may be pivotable between an erected position in which the first foot is oriented generally perpendicular to the generally horizontal bar and a folded position in which the first foot is substantially coplanar with the generally horizontal bar. A second leg may be pivotably coupled to a second end of the generally horizontal bar. The second leg may include a generally horizontally extending second foot and/or the second leg may be pivotable between an erected position in which the second foot is oriented generally perpendicular to the generally horizontal bar and a folded position in which the second foot is substantially coplanar with the generally horizontal bar.

Abstract: Adjustable-weight exercise devices are disclosed. An example adjustable-weight exercise device may include an exercise device body; a generally cylindrical cavity extending into the exercise device body and comprising at least one engagement feature; and a generally cylindrical weight insert configured to be slidably received the cavity and comprising a corresponding engagement feature. The engagement feature and the corresponding engagement feature may be configured to releasably engage each other to selectively retain the generally cylindrical weight insert within the generally cylindrical cavity.
