A swimming machine, also known as a resistance swimming apparatus, is a self-contained device powered by a pump, designed to facilitate stationary swimming for athletes or recreational users. This can be achieved by either propelling water past the swimmer or providing support for the swimmer, either within a water environment or on dry land.^[1]

There are multiple variants of a swimming machine including countercurrent machines, hybrid systems, pressure-driven machines, swim spas, and volume driven machines.^[1]
