<p>The invention relates to a multifunctional trainer for strength training. The trainer comprises a body (1), a counterforce unit (2) for generating a counterforce to resist the exercise movements, a set of movement arms (3 1 , 3 2 ) supported to the body (1) for performing different exercise movements, and a set of elongated tensile elements (4 1 , 4 2 ), arranged to act between the counterforce unit (2) and the movement arms (3 1 , 3 2 ) for applying the counterforce resisting each exercise movement from the counterforce unit to the movement arms. The trainer comprises an automatic mechanical coupler (5), to which the tensile elements (4 1 , 4 2 ) are connected, and which coupler is adapted to, immediately at start of each exercise movement, automatically couple the tensile element corresponding to each separate movement arm for said exercise movement, to the counterforce unit (2) in a force-applying manner, for applying the counterforce of the counterforce unit to said exercise movement, without the need for manual connection prior to performing said exercise movement, and without affecting, during said exercise movement, the tensile elements connected to the other movement arms, which are not subject to tension during said exercise movement.</p> |
