Genin Medical 2000

MULTI FORM First French Manufacturer of Fitness Equipment, Turned 20

20 years of experience, Know-how and innovation, 20 years during which the company has continiously developped new products thanks to its understanding of its customers, of the expectations of clubs, and its investment in new technologies (creation of CAD, robot welding, ...) but also thank to the investment of a whole team that works daily to accomplish the production and to reach the customer satisfaction. The watchword of our development could be one of our latest range of fitness machines: NEXT, released exclusively at the show Form'expo Mondial Body Fitness 2009, the NEXT line allows a concentric and / or eccentric muscles training.

Why using this technique?

There is a large number of articles that refer to this technique, for example, "The policy statement of the American College of Sports Medicine (1)" Most resistance training programs include primarily dynamic repetitions with both concentric (muscle shortening) and eccentric (muscle lengthening) muscle actions. Greater force per unit of muscle size is produced during eccentric actions (6) Eccentric actions are also more neuromuscularly efficient (3,6) less metabolically demanding (4) and more conducive to hypertrophy (5)]... “Dynamic muscular strength improvements are greatest when eccentric actions are included in the repetition movement (2)”.

For whom?

This technique of eccentric muscle training has been known and recognized for many years, especially in professional sport research and rehabilitation where many articles attest to its results. More generally, this technique is dedicated for any athlete who practice muscle training regularly and with caution. It is a great way to improve ones performance in a supervised training.


NEXT offers a "two in one" machine, used either with a "classic" automatic weight stack load or with an “assisted load". This one will be setup from the working position and allow to retain a greater load than that has been raised. The range NEXT therefore allows to practice a modern muscle training to all person’s levels.
