Abstract: A device (1) for the assisted execution of a physical exercise by a user includes a sitting area (2) in which the user is accommodated. Leg movement devices (3) are suitable for accommodating the right and left foot, respectively, of the user to move them according to a rotatory trajectory with respect to a leg rotation axis (G-G). Arm movement devices (4) are graspable by the user with the right and left hand, respectively, to move them according to a rotatory trajectory with respect to an arm rotation axis (B-B) that extends parallel to the leg rotation axis (G-G). The device further includes an exercise controller (5) operatively connected to the leg movement devices (3) and to the arm movement devices (4) to transmit the respective movement simultaneously.
