Elliptical trainers were first introduced by Precor. They make exceptionally stable and robust machines for both the commercial and home markets. The company uses high-quality components and manufacturing methods based on practical research to develop all fitness equipment. The company has been in the fitness equipment industry for over 25 years and has developed many innovative fitness machines such as ellipticals and adaptive motion trainers. Its machines are widely used in health clubs, gyms, hotels, hospitals and rehabilitation centers.

CrossRamp technology is the main important feature in almost all high-quality Precor elliptical machines. With this technology, the user can adjust the incline to the desired level. This allows the user to individually target all lower body muscle groups during exercise. Magnetic resistance type, longer stride length and long warranty are other important features of all Precor premium elliptical machines. Precor ellipticals range in price from medium to high, keeping the requirements of serious fitness-minded individuals.
