Rowing is a total body workout.
Rowing only looks like an upper body sport. Although upper body strength is important, the strength of the rowing stroke comes from the legs. Rowing is one of the few athletic activities that involves all of the body’s major muscle groups. It is a great aerobic workout, in the same vein as cross-country skiing, and is a low-impact sport on the joints.
Rowers are among the world’s best athletes.
Rowing looks graceful, elegant and sometimes effortless when it is done well. Don’t be fooled. Rowers haven’t been called the world’s most physically fit athletes for nothing. The sport demands endurance, strength, balance, mental discipline, and an ability to continue on when your body is demanding that you stop.
Sweep (like a broom) and Sculling (with a “c”).
There are two basic types of rowing: sweep rowing and sculling. In sweep rowing, athletes hold one oar with both hands. In sculling, the athletes have two oars, one in each hand.
