<p>The system comprises a weight (1) which is gradually displaceable along a rocking guide (10) which oscillates when the user performs an exercise by pulling the same weight (1) during the exercise for each determined position of the weight (1) along the rocking guide (10). The displacement of the weight (1) along the rocking guide (10) increases or reduces gradually the weight for the exercise of the user, through a combination of a resistance arm consisting of the weight (1) displaceable along the rocking guide (10) and of two power (4) and resistance (5) wheels associated to each other through a transmission means (7), the power wheel (4) being connected to the user-actuated means (13, 14) and the resistance wheel (5) being connected to the shaft (3) of the rocking guide (10).</p> |
