In an exercise apparatus comprising a fixed support member ( 3 ) and a moving part ( 2 ) which can perform movements correlated to the exchange of forces between a user and the apparatus, a support device ( 1 ) comprises: elastic supporting means ( 4 ); means ( 6 ) for damping the movements of the moving part ( 2 ) and adjusting means ( 7 ). The damping means ( 6 ) are arranged parallel with the supporting means ( 4 ) and comprise a magnetic actuator ( 8 ), in which a first, moving component ( 9 ) has an electroconductive element ( 11 ), and a second, fixed component ( 10 ) comprises a permanent magnet ( 12 ) and a non-permanent magnet ( 13 ) connected to one another to form at least one air gap ( 14 ) which houses the electroconductive element ( 11 ). Electrical energizing of the electroconductive element ( 11 ), whether generated or induced, applies to the first component ( 9 ) of the actuator ( 8 ) a reactive magnetic force which opposes the translational movement.
