You get the Hobie Mirage Eclipse. The premise for this product by the Hobie Cat Company (which makes watercraft, not cats) is that paddleboarding can be a vigorous form of exercise when users pedal stairs that flap fins on the bottom to provide locomotion. You steer it by squeezing handlebar-mounted levers, which control the rudder. It comes with an optional crate that straps onto the back end for storing snacks or fishing gear.
Unlike a conventional stairclimber, the Mirage Eclipse offers more adventure than a stationary device inside a gym.
