A rowing workout can produce sustainable results without negatively impacting muscles and joints. With a reported average of five hundred to a thousand calories burned per workout, rowing machines are the hottest new fitness trend in the industry. Because of this, manufacturers are working overtime to produce a wide variety of styles and types of row machines, all of which can offer an effective low-impact total body workout. With so many choices of models, it can be confusing for beginners to choose the right type. Most consumers automatically choose the cheapest rower, however, cheaper models often feature piston resistance, which is considered the worst type of technology because the workouts are uncomfortable and the machine itself is often poorly designed.
