An exercise system can include an exercise device and a sliding board that when used together may help patients regain strength and mobility during lower limb rehabilitative exercises. The exercise device may include a foot support body; a support wall extending vertically upward on one side of the foot support; a divider wall extending vertically upward from the support body and extending transversely from an opposing side of the foot support body; an ankle bed rest defined by a space from the support wall and around the divider wall; and a smooth bottom surface. The sliding board can have a smooth top surface that is slidable relative to the smooth bottom surface of the exercise device.

Certain exemplary embodiments can provide a system comprising a treadmill. The treadmill comprises a track and a weight stack. The weight stack is coupled to a harness coupleable to a user, the harness constructed to simulate pulling a weighted sled when coupled to the user as the user utilizes the treadmill. The weight stack is coupled to a handle graspable by the user, the harness constructed to simulate pushing a weighted sled when the user grasps the handle as the user utilizes the treadmill.

An exercise apparatus is provided having a handle pivotally attached to a flat base, the base and handle each configured for receiving optional weights, the flat base providing resistance when the handle moves the base along a surface.

A weight training sled (100) characterized by one or more of (A) rotatable wheels (130) in contact with ground, (B) curvilinear push handles (140) with comfortably spaced, and inwardly and/or downwardly angled hand grips (143), and (C) an elevated tow hook (160).

A seated exercise system is provided having a pair of sliders devices, each slider device including a body portion having a continuous side wall and a support surface. The support surface is sized and shaped to receive a foot of a user. A floor portion configured to slide on a floor surface during operation is provided. A grip portion is attached to the support surface, wherein the grip portion is constructed from a traction material providing traction to the foot during operation. Motion tracking components configured to detect movement data of the foot and during operation are provided. At least one slider of the pair of floor sliders is configured to communicate the detected movement data to the other slider; and, wherein at least one slider of the pair of floor sliders includes a wireless communication device configured to send the detected movement data a computerized device such that the detected movement data is available to the user.

A low friction rehabilitation board having an integral band retaining feature is described. The rehabilitation board may have a coefficient of static friction of no more than about 0.5 and in some embodiments no more than about 0.06. The rehabilitation board has a plurality of band retaining feature configured along one or both ends and may be an integral band retaining features being formed in the board. Additionally, the rehabilitation may include one or more band retaining features on one or both sides of the board. The unique configuration of the band retaining features enables rehabilitation method heretofore not possible with a single board. Resistance bands may be retained in the band retaining features and coupled to a user's limb, such as a foot or ankle, to resist motion, such as sliding or extending the foot along the low friction surface of the rehabilitation board.

An exercise device having a sled or wheelbarrow configuration comprises a frame that is pushed across a support surface by a user. The frame carries a wheel that movably supports the frame in the wheelbarrow configuration and at least one skid that movably supports the frame in the skid configuration. A pair of handles is selectively repositionable on the frame from a vertical orientation used in the sled configuration and a horizontal orientation used in the wheelbarrow configuration to quickly and easily convert the device between its different configurations. The frame has a carriage that supports a plurality of exercise weight members with the carriage being movable in a fore-and-aft direction on the frame for changing the effort required from the user to push the frame.

A selectorized dumbbell includes a horizontal stack of nested left weight plates and a horizontal stack of spaced right weight plates with the stacks being separated by a gap into which a handle may be inserted. A selector is movable into different positions relative to the handle to vary how many nested left and right weight plates from the stacks thereof are coupled to the handle to vary the exercise mass of the handle. Each left weight plate has a counterpart right weight plate counterpart which are coupled together by at least one interconnecting member having a first keyhole slot connection between the left end of the interconnecting member and the left weight plate and a second keyhole slot connection between the right end of the interconnecting member and the right weight plate.

A durable and impact-resistant exercise apparatus that is portable, modular, stackable, and weight-adjustable to allow a user to perform a variety of isolated lower body, core, and upper body resistance training exercises as well as full-body strength training exercises to improve a fitness of the user. The exercise apparatus is configured both as a platform for supporting the user during a first plurality of exercises as well as a weighted body for being lifted or moved by the user during a second plurality of exercises.

A training sled configurable for adding weights in some embodiments to increase friction and provide for weight-training by lifting portions of the sled. Sled components are slidably or pivotably connected to permit lifting a shoulder member of the sled to different heights and to achieve an optimal training angle. The training sled having an accelerometer, sensor unit and display for sensing, determining and displaying the force of impact and movement of the training sled.
