Am I the only person who loves the rowing machine? I really do love these machines, I think they are fantastic for cardio and one of the few ways to get some good upper body work in while doing cardio.
These machines take some getting used to, or working up to. I hadn't spent any time on one in more than a year, and I got on one the other day after finishing a bicep workout, and I lasted 8 minutes before I thought I was going to die!
Indoor rowing primarily works the cardiovasular systems with typical workouts consisting of steady pieces of 20-40 minutes. Like other forms of cardio focused exercise, interval training is also commonly used in indoor rowing. While cardio focused, rowing also stresses many muscle groups throughout the body anaerobically, thus rowing is often referred to as a strength-endurance sport.
Unlike high impact exercises, which can damage knees and the connective tissues of the lower body, rowing's most common injury site is the lower back. Proper technique is a necessity for staying injury free, with a focus on both mechanics and breathing, as correct rhythm, exhaling on the drive and inhaling on the recovery, is a stabilizing force for the upper body. Non-rowers commonly overemphasize the muscles of the upper body, while correct technique uses the large muscle of the thighs to drive much of the stroke. Also, good technique requires that the angle of the upper body is never too far forward, nor too far back, both of which jeopardize the lower back and compression injuries on the knees and hip flexor muscles.
In addition to the high levels of fitness attained, rowing is an intense calorie-burning exercise. Although rowers with less ability and training will burn fewer calories, the ergometer is an excellent tool for use in a weight-loss program.
The standard measurement of speed on an ergometer is generally known as the "split," or the amount of time in minutes and seconds required to travel 500 meters at the current pace. For example, a 2:00 split would correspond to a 2:00 time for a 500 meter race, or an 8:00 time for a 2 kilometer race. The split does not necessarily correspond to how many strokes the rower takes (the "rating") since strokes can vary in power.
