1. A gymnastic machine comprising
a frame having a base, wherein said base comprises a first and a second longitudinal member,
a closed-circuit sliding-belt associated with said base, arranged between said first and said second longitudinal member,
a transmission assembly having an electric motor, configured to move said closed-circuit sliding-belt, and
at least one dragging roller configured to drag said closed-circuit sliding-belt in a sliding direction;
wherein said transmission assembly comprises motion transfer members for transferring the motion of said electric motor to said at least one dragging roller
wherein said electric motor is arranged below said closed-circuit sliding-belt;
wherein the closed-circuit sliding-belt is configured to allow a user to execute a gymnastic exercise;
wherein said frame comprises at least one horizontal bar perpendicularly arranged, and coupled with said first and second side member, wherein said electric motor is fastened to said at least one horizontal bar;
wherein said at least one dragging roller comprises a coupling portion, said electric motor comprises a pinion connected to the driving shaft;
said motion transfer members comprise a driving belt, engaged with said coupling portion of said at least one dragging roller and with said pinion of said electric motor.
