Challenge your muscular and cardiovascular endurance with the Water Rowing Machine by Sunny Health & Fitness. Enjoy maximum stability when you strap your feet onto the adjustable foot pads. Position the leveling endcaps before using the water rower to keep the water rower machine stable across home surfaces. Grab the padded, anti-fatigue handlebar as you quietly glide along the 48-inch aluminum slide rail. Feel confident performing intense workouts on the durable frame, which supports a maximum user weight of 265 lb. Pull against the belt-drive and elastic rope mechanism with each stroke to push 4 blades through the water tank. Four blades push more water than the standard two, creating more progressive resistance per stroke. Gain even more control over the water rowing resistance by adjusting the water tank level.
