The one at my gym had a dial to adjust resistance. It did something to change how the water inside moved around, I think. I tried googling "water rower" to find the model, and I couldn't find it. I can say that it was different from most water rowers I'm finding though. Most of them have the water tank horizontal, while the one I used had it vertical. It looked very similar to this: https://sunnyhealthfitness.com/products/water-rowing-machine-sf-rw5809 https://sunnyhealthfitness.com/products/water-rowing-machine... EDIT: Actually, it more closely resembled this one: https://firstdegreefitness.com/shop/fluidrower/vx-2/ https://firstdegreefitness.com/shop/fluidrower/vx-2/
