Gymnastic machine for training the trunk muscles, comprising improved levers

A gymnastic machine for training trunk muscles and shoulder cingulum comprising:

• a frame configured to rest the gymnastic machine on a ground or on a base;
• a first lever comprising a first handle configured to be gripped by a user, the first lever being pivotally coupled to the frame at a first fixed fulcrum and configured to rotate around the first fixed fulcrum about a first substantially vertical axis from a first position to a second position;
• a second lever comprising a second handle configured to be gripped by the user, the second lever being coupled to the frame at a second fixed fulcrum and configured to rotate around the second fixed fulcrum about a second substantially vertical axis from a first position to a second position, wherein the rotation of the second lever is opposite to the rotation of the first lever;
• a gravitational resistant device or an electromagnetic device configured to oppose resistance during movement of the first and second levers from their respective first positions to their respective second positions;
• one or more cables configured to connect the first and second levers to the gravitational resistant device or the electromagnetic device;
• a first support surface coupled to the first lever;
• a second support surface coupled to the second lever;
• and
• a spacer on which a torso of the user rests when the user performs an exercise,
• wherein the first support surface, when the gymnastic machine is in use, is configured to extend below a first forearm of the user, to act as a reference for a position in which a first arm of the user is kept during execution of the exercise, and
• wherein the second support surface, when the gymnastic machine is in use, is configured to extend below a second forearm of the user, to act as a reference for the position in which a second arm of the user is kept during execution of the exercise.
