Function plays a large role in defining good design. When designers look at an object, they don't just consider its aesthetic appearance; they should also challenge it to be more versatile, to respond to the user's need, or to achieve its purpose more elegantly. Good design has the capacity to solve problems that sometimes we didn't even know we had. This is one of the ways design touches and enriches our everyday life.
In the empty-lung technique, rowers inhale during the drive, and exhale during the recovery so that they have empty lungs at the catch. Because the knees come up to the chest when the lungs are empty, this technique allows the rower to reach a little bit further than if the lungs were full of air. Full lungs at the release also can help the rower to maintain a straighter back, a style encouraged by many coaches.
According to Men’s Total Fitness, rowing machines are not only great for aerobic workouts, but they also work all of your body's major muscle groups. What’s more, you don’t have to go to the gym to work out on a rowing machine, as many manufacturers make high-quality rowing machines -- and even rowing machines that fold up for easy storage -- that are suitable for home use. Two popular types of rowing machines are the water rower and the air rower.

In sweep or sweep-oar rowing, each rower has one oar, held with both hands. This is generally done in pairs, fours, and eights. In some regions of the world, each rower in a sweep boat is referred to either as port or starboard, depending on which side of the boat the rower's oar extends to. In other regions, the port side is referred to as stroke side, and the starboard side as bow side; this applies even if the stroke oarsman is rowing on bow side and/or the bow oarsman on stroke side.
