Rowing machine (rower)

More and more people are recognizing the benefits of regular exercise, and the exercise industry has experienced rapid growth as a result. Training rowing machines had been used widely for decades. They mainly are used to strengthen muscles on hands, legs, chests, waists and backs thus can be deemed as training machines for whole body. Weight training machines typically include a mechanical member that the user repeatedly moves along a prescribed path for exercise. Conventionally, movement of the mechanical member is resisted in some fashion to render the movement more difficult and thereby intensify the exercise. The movement of the mechanical member determines what muscle or muscle groups are to be involved in the exercise. One popular exercise movement, both for aerobic and weight training, is the rowing motion, in which a seated exerciser extends his arms to grasp a handle or other grasping device and pulls the handle toward his body. This exercise movement tends to work the muscles of the upper back (e.g. the middle trapezius, rear deltoids, teres major, latissimus dorsi, and rhomboids) and the biceps. Rowing exercise machines are becoming very popular and commonplace. A rowing exercising machine is an indoor exercising device which permits the user to imitate the movements of rowing a boat. Since such a device can provide excellent exercising effects, it has been widely used by the consumers. Rowing machines allow the user to exercise his arms, shoulders, chest and legs by simulating the movement required to propel a rowboat. These machines could provide a more complete exercise program if adapted to permit the user to more fully exercise his stomach and thighs. The rowing exercising machine generally comprises rowing rods, sliding rail and seat pat, in which, the seat pad is supported by the sliding rail and is able to slide back and forth upon the sliding rail. When using the rowing exercising machine, the user can sit on the seat pad and rows two rowing rods with both hands in conjunction with the movement of the legs to move his body forward and backward by means of sliding the seat pad along the sliding rail. Most rowing machines use pneumatic cylinders to provide the resistance to a rowing stroke. The user sits upon a seat that slides back and forth along a rail, anchors his feet, and moves handles attached to the cylinder or cylinders. This type of rowing exercise machine provides a poor imitation of the actual body movements and muscle development that is needed for competitive rowing.
