In sailing, it is the task of the grinder to transform wind into propulsion by hoisting the sails as quickly as possible. Grinders perform the backbreaking work on board- they are truly top athletes! Exerting physical strength and endurance, the grinders race to turn the winches on sea-going yachts to raise the sails, with a classic crank motion. 

The NOHrD WaterGrinder brings this intensive sport to your home, enabling you to achieve the impressive fitness levels of a racing grinder, without having to forego the element of water!

The WaterGrinder is easy to use while providing a wide range of exercise possibilities. Its elegant, drop-shape wooden frame is a true eye-catcher in the home or studio.

The WaterGrinder’s paddle is ergonomically shaped, producing the machine’s resistance in its water tank. Water resistance is self-determined, meaning, with each move it can precisely adjust to strength input: the harder you crank the hand pedals, the higher the resistance.
