A gymnastic
machine (1) comprising: a frame (2) defining at least a support area (3) for the back of a user inclined with respect to the vertical, at least a platform (7) for the support of the feet, this too inclined with respect to the vertical, where the support area (3) and the platform (7) are inclined on opposite sides with respect to the vertical and are mutually convergent downwards, at least a
work unit (4) associated with the frame (2) and having a loading unit (5) for the execution of a gymnastic exercise and movement means (6) for moving the loading unit (5), where the
work unit (4) comprises a bearing element (4a) associated with the frame (2) and the movement means comprise at least a grip element (8) which can be gripped by the user, connected mobile to the bearing element (4a) and connected in a kinematic manner to the loading unit (5), the shift of the grip element (8) causing the loading unit (5) to shift, wherein the
machine (1) is without a seat, the platform (7) being adapted to support at least partly the weight of the user, the latter holding himself / herself upright, and in that the movement means (6) comprise at least a
pulley (9a, 9b) placed between the grip element (8) and the loading unit (5) and connected in a kinematic manner to the latter by means of at least a flexible element (11a, 11b), said
pulley (9a, 9b) being keyed onto a shaft (10) supported in rotation by the bearing element (4a), and wherein it comprises safety means (13) which can be operated to lock the shaft (10) in a plurality of predefined angular positions.
