Compared with indoor fitness equipment such as treadmills, rowing machines have less impact on the knee joints because they have no landing action, and efficiently exercise 85% of the muscles of the upper limbs, lower limbs, waist and abdomen, back, etc., becoming the new favorite of the fitness industry. Starting from the hydraulic resistance rowing machine invented by W.B. Curtis in 1872 in the early days, the rowing machine industry has been continuously iterated and has been subdivided into hydraulic, magnetoresistive, wind-resistant, magnetron-controlled wind-resistant, and water-resistant.
 
Concept 2 and WaterRower are both in the 80s of the 20th century began to develop rowing machines in the United States old brands, when the emerging brands choose hydraulic, reluctance rowing machines with relatively low technical content, expand their product matrix, and seize the low-end market below the price of 4000 yuan, these two old brands still adhere to the field of wind resistance or water resistance rowing machines with high technical thresholds, focus on the high-end market with a price of more than 8000 yuan, and simulate the rowing of products with real sense and professionalism. To be the benchmark position of the industry.
 
Founded in 1972 by Dick and Peter Dreissigacker, Concept 2 is a leading manufacturer of indoor rowing machines and oars, and its carbon fibre oars have been widely used by World Rowing Championships and Olympians. As the pioneer of the wind resistance rowing machine, its unique bellows design is at the first-class level in the industry, the flywheel is equipped with a half-moon spiral damper, and the bellows shell is a paddle with a scale, the user can change the size of the air inlet with a slight flick, complete 10 levels of graded drag regulation, high smoothness of action, and good operation convenience. In general, users can adjust the paddle to 3 to 5 to get the resistance to meet their daily training needs, and start sweating after 10 minutes of paddling.
 
Data monitors are one of the must-haves for many fitness equipment today, providing timely feedback on the user's workout status, and rowing machines are no exception. The Performance Monitor PM5 is the latest generation component of the Concept 2 and is professionally designed to measure and interact with data. In addition to the comprehensive display of pace, watts, stroke rate (spm), calories and other data, and the use of "Just Row" mode to set up various workout plans, its Bluetooth and ANT wireless connectivity function, which can be matched with a heart rate chest strap or connected to the Venue Race app, supports the competition use of more than two rowing machines, and has a small data error, so it is often used as a special equipment for indoor rowing machine competitions.
 
Although the Concept 2 rowing machine is expensive, generally ranging from 7850 to 10400 yuan, its popularity remains high, and the product ranks among the top 10 in the sales list of Meiya rowing machines. Unlike the high-density silk webbing materials commonly used in rowing machines on the market, the D-type and E-type of the Concept 2 use nickel-plated steel chains, which improves durability and smoothness, and improves the pulling sensation of muscles. The Dynamic model is more optimized, using a semi-enveloped synthetic fiber paddle rope, which is lighter than the steel chain and 15 times stronger than steel, and can respond quickly in high swooping movements, making the user's rowing movements more agile and effective.
 
Featured in Consumer Reports, the Model D features the Concept 2's superior bellows design and PM5 performance monitor, with a quick-release frame locking device that allows the user to easily disassemble the equipment into two parts without the need for tools, saving storage space, and working with front rollers for easy handling. In addition, the net weight of the D-type priced at 7850 yuan is 26kg, which is 3 to 16kg lighter than other models, and it is the lightest and lowest priced one in the whole product line.
 
The E-type, priced at 9600 yuan, is an upgraded version of the D-type, with a seat height of 51cm, which is 15cm higher than the D-type, which is more suitable for tall users. In terms of the material used for the legs, the E-type replaces the aluminum alloy with a stronger welded steel, which improves the supporting capacity, and the slightly heavier ones are not easy to shake when using the rowing machine. In addition, the E-type has also been optimized on the tensile parts, and the nickel-plated steel chain is coated with a fully enclosed shell to ensure a smooth tensile feeling and easy to care for.
 
In addition to the pleasant sound of the water flow without the water resistance rowing machine, the Dynamic can be called the one with the highest degree of rowing fidelity among the wind resistance types.
 
The common rowing machine pedal is fixed, mainly relying on the seat to move greatly and pull the rope movement, while the foot pedal of this model can float freely along the aluminum alloy guide rail, and the slide moves relatively small, so that the rowing action is more dynamic and the user consumes more heat.
 
However, in order to achieve the above effect, the Dynamic type, which has the highest price, sacrifices the frame locking design of the D and E models, and can only be stored as a whole machine. To compensate for this shortcoming, Sunny has shortened the length of the Dynamic Type by 51 cm, and the floor space is 0.3 square meters less than that of the D and E types in the unfolded state. However, the non-detachable Dynamic type is not as space-saving as the D and E types, so the D and E models are more suitable for consumers with limited activity space.
 
It is worth mentioning that in addition to the resistance adjustment of the wind resistance rowing machine, it can also adjust the exercise intensity by changing the frequency and strength of the paddle pulling action, which is more natural, smooth and without stiffness than the resistance adjustment of the hydraulic and reluctance rowing machine. However, due to the fact that the wind resistance rowing machine uses a flywheel with fan blades to rotate and squeeze the air in the bellows to produce resistance, its physical structure is destined to bring a certain amount of wind noise.
