1. An exercise machine comprising:
- an element for the application of a force by a user;
a plurality of weights for countering the force applied on the element, the weights being configured to stack on one another and the weights being connected to the element;
a load regulator comprising a pulling bar, having a longitudinal extension in a predetermined direction, connected to the element, and designed to slide in a longitudinal slot forming a passage for the pulling bar at the plurality of weights, the pulling bar being associated with the weights and the pulling bar having a plurality of grooves along its longitudinal extension, wherein the load regulator comprises elastic means comprising a “
U”
-shaped spring with an open end, the elastic means being fixed to the weights and able to move between a closed position, in which they connect the weight on which they are positioned to the pulling bar, and an open position in which they release the weight on which they are positioned from the pulling bar; and
the regulator comprising a selection rod able to move parallel with the direction, said selection rod being designed to selectively cause the elastic means to adopt respectively the closed or open position, wherein the spring is wrapped around the pulling bar in one of the grooves and the open end is towards the selection rod.
