The horizontal movement of the water when a wave passes is approximately equal to the up and down movement of the water. If you are on flat water and are parallel to waves made by a passing boat, your boat will move side-to-side as much as up-and–down as the wave passes under you. The side-to-side movement actually creates most of the difficulty in balancing the boat in such a situation. However, under typical conditions in the bay there can be such varied wave action that you can’t easily distinguish horizontal and vertical motion.
As with any fitness activity, it’s important to exercise with proper technique, however. The big muscles in the legs are where most of the workout action should be. Injury to the lower back can occur from bending too far forward in the row. It’s best to maintain a upright 90 degree angle to the rowing machine’s seat and slider bar. Using the legs for the motion rather than relying as heavily on the back or arms can help reduce the chance of muscle pulls or other related injuries. Always check with a physician before starting any new fitness regimen.
The benefit of a water resistance rower is that it most closely simulates a boat moving through water. Rowing resistance comes from the effect of fluid drag acting on the boat; in other words, resistance increases according to stroke rate. The patented WaterFlywheel emulates this naturally self-paced benefit of rowing. This is a workout with immediate benefits, regardless of your level of experience! Please also note that you can adjust the workout intensity by changing the amount of water in the tank. The more water, the higher the effort level required.
