A golf practice device, for practicing the back swing of a golf swing, includes a folding device, which can be arranged so as to be inclined against the horizontal about a predetermined angle. The angle is the angle of inclination of the swing plane of the back swing. The device also includes a trigger device, which cooperates with the folding device. The trigger device is adapted to lock the folding device in the predetermined angle in a locked mode and to release the locking of the folding device in a trigger mode. The folding device can be folded downwards about a pivot axis in response to releasing the locking device.
