An exercise device is described which includes a platform having a first end and a second end opposite the first end; first and second wheels, wherein the first wheel is positioned proximate the first end and the second wheel is positioned proximate the second end and the first and second wheels are configured to roll across a surface as the exercise device is displaced along the surface; a first motor configured to apply a first torque to the first wheel where the magnitude of the first torque is related to the distance of the exercise device from a zero position and the direction of the first torque urges movement of the exercise device toward the zero position. Versions are also described with more wheels and more motors.

A variable difficulty balance board for standing desk and fitness use is provided. The balance board facilitates the conditioning and rehabilitation of the nerves, bones, muscles, and joints of the body by limiting the range of motion and biomechanical forces around the longitudinal and lateral axes. The balance board comprises a deck, a fulcrum receiver, and a fulcrum insert. The fulcrum insert is press-fit into a fulcrum cavity of the fulcrum receiver. The fulcrum insert extends outward from the fulcrum receiver and provides an area where the balance board can pivot. The fulcrum insert may be replaced by the user such that it may occupy either a first orientation or a second orientation within the fulcrum cavity. The first orientation and the second orientation configures the fulcrum insert such that it provides a lateral or longitudinal axis of balance relative to the deck, respectively.

The invention relates to a balance base for a rowing machine. The base is used as a stand for the rowing machine, and the rowing machine can be positioned thereon in a fixed manner. At least one spring element is provided, wherein the at least one spring element is arranged between an upper frame and a lower frame, and the at least one spring element comprises an elastic or viscoelastic material, the tilting rigidity of which is both lower than the tensile-compressive rigidity of the spring and lower than the shear stiffness of the spring. Additionally, a form-fitting or force-fitting fixture of the upper frame to the rowing machine is provided.
