Competitive rowing athletes use the Concept2 Dynamic RowErg indoor rower to refine their on-water stroke. When you use the Dynamic, your body is relatively stationary while the feet move. When you row on the Dynamic, you build body control, early preparation and good connection between the body and foostretchers during the drive. You may find the Dynamic a good fit if you are looking to refine your on-water technique and high stroke-rate rowing.
