Not sure about strokes but swimming is a low impact form of exercise compared to running
I've heard it's great for strengthening muscles. Do you think that's true?

Science.
Swimming relies on the nearly neutral buoyancy of the human body. On average, the body has a relative density of 0.98 compared to water, which causes the body to float. However, buoyancy varies on the basis of body composition, lung inflation, and the salinity of the water. Higher levels of body fat and saltier water both lower the relative density of the body and increase its buoyancy.
Since the human body is
-natural swimming environment. They were followed by paddle-wheel and propeller-driven machines, which were popularized by Endless Pools. These generated a smoother stream of water. Many users find them easy to swim in, but the machines are also criticized for being expensive, noisy, and wasteful of energy (consuming 6.5 kW to 11 kW of electricity just to set the water in motion).
Finally, there are exercise machines which allow a person to remain on dry land while simulating certain swimming strokes.
