Concept2 Indoor Rowers combine the feel of rowing on water with the convenience of training indoors. The Model E Indoor Rower offers presence and durability with its 20 " frame height and powder coat with glossy finish. From a practical standpoint, the higher frame means easier on-and-off for those with tired knees or mobility considerations. One-piece leg design for both the front and rear legs results in stability and a sure, solid feel.
