Abstract: An adjustable foot plate for rowing machines is provided. The foot plate includes two platforms for placing a user's feet thereon when using the rowing machine. Each platform includes a strap, a heel counter and lengthening member for adjusting a distance between the strap and the heel counter to align the widest part of the user's foot with the strap. The platforms are laterally adjustable by a linear drive mechanism to vary a distance between the user's feet to better accommodate users of varying size/height. Lateral adjustment of the platforms may also provide for the user to exercise different muscle groups as part of an exercise regime.

Abstract: A module system for use as an underground stormwater retention basin, where the module system parts consist of a plurality of watertight three-dimensional units such as cuboids. Each of the watertight three-dimensional units has one or more through holes selected from a female through hole and a male through hole. A female through hole is for insertion of a flange of a male through hole. A male through hole has a flange for insertion into a female through hole. The disclosure further discloses various additional parts for the module system of the underground stormwater retention basin, to methods of building an underground stormwater retention basin and to a use of an underground stormwater retention basin.

Abstract: A system having networked exercise devices that can have a shared virtual exercise session for training, collaboration or competition. The exercise devices each have adjustable difficulty setting and a touch screen for displaying different virtual exercise sessions. The touch screen can display a representation, such as one or more avatars, that represent users of the exercise devices, and that have a virtual speed in proportion to exercise performance on the exercise devices. Dynamic adjustment can be made based on the collective performance of the exercise devices, to cause a same adjustment to a respective current difficulty setting of at least one, two or more exercise devices during the shared virtual exercise session. Virtual training can be provided by way of a chaser animation that chases the representation of the exercise devices, the chaser animation having a virtual speed in dependence of exercise performance of users of the exercise devices.
