There is provided a plank exercise device including a support portion adapted to receive arms or hands of a person and adapted to receive a display device, a destabilizer connected to the support portion, and a stationary base adapted to hold the destabilizer.

A stationary exercise machine comprising an ergonomic device attached to a trolley slidably connected to an inclinable surface. The trolley connected to one or more resistance mechanisms generally opposing one another or gravity. The ergonomic device comprised of a balance board, seat, carriage, bike, or other apparatus intended to carry a user. A method where the user pumps, moving one's body weight in a rhythmic up-and-down, back-and-forth motion, to repetitively move the ergonomic device along the inclinable surface while standing, squatting, kneeling, sitting, laying, or otherwise resting, balancing, or riding on the ergonomic device, and where at least one resistance mechanism stores and releases mechanical energy produced by the user's pumping action. The resistance mechanisms can also be connected or disconnected, or user-controlled or automated to facilitate alternative methods of use, such as use as a balance board, rower, reformer, gravity-based exerciser, elastic resistance trainer, or flywheel resistance trainer.

A sliding balance board has an eccentrically mounted center wheel as a pivotable central balancing member, a wheel with one-way sprag clutch bearings mounted near the left end of the board and a wheel with one-way sprag clutch bearings mounted near the right end of the board. A user balances himself/herself on the board, and yet slides the board to the left and right, back and forth by shifting his/her weight left and right, synchronized to the rocking motion of the eccentrically mounted center wheel.

An exercise machine with multiple platforms for an exerciser to perform a variety of exercises generally includes an elongated frame structure supporting stationary first and second end platforms, a longitudinal rail extending between the end platforms and having an upper surface comprising a central platform, and a slideable carriage platform that reciprocates on the rail over the central platform and between the end platforms. The platforms provide multiple support surfaces at multiple elevations on which exercisers can position parts of their bodies during exercise. The platforms may be provided with positioning indices and provide continuous support surfaces over substantially the entire length of the exercise machine. The central platform may be provided with finger grips for exercisers to grasp. One or more mounting platforms may be provided to facilitate mounting and dismounting of the exercise machine.

There is provided a treadmill deck (10) for supporting at least part of a treadmill belt, the deck (10) including a foot strike area (12) disposed towards one end of the deck, and a foot take-off area (14) disposed towards another end of the deck, an upper surface of one of the areas including: a lateral inward or outward slope, which provides a lateral gradient across at least part of the area (12, 14), and an upper surface of the other of the areas (14, 12) including one of: a laterally horizontal surface or a lateral inward or outward slope, which provides a lateral gradient across at least part of that other area (14, 12).

A stretching device includes a heel platform sized and shaped to support a heel of a foot of a person thereon. The stretching device also includes a ball platform sized and shaped to support a ball of a foot of a person thereon. The ball platform is angularly offset relative to the heel platform. The stretching device includes one or more connection members connecting the heel platform to the ball platform. The stretching device includes an extension slot connected to the ball platform. The stretching device includes a stretching device extension. The stretching device extension includes an extension platform arranged coplanar with the ball platform. The stretching device extension includes an extension insert arranged within and selectively removable from the extension slot.
