All subjects with lumbar hyperlordosis and quadratus quadratus lumborum retraction, working with this machine with reduced amplitude movements and low load, will gradually see the stiffness reduce with great relief. This unblocking action will result in an advantageous recovery of the length of the retracted muscles, with a marked improvement in posture and thus a feeling of greater well-being. Work for the same muscles can be performed standing and seated with a wooden pole, with a barbell and free-body. In all these cases, the activity of the quadratus quadratus of the loins is accentuated and thus the lumbar action due to the posture (standing work), and the difficulty of symmetrically adjusting the rotation and amplitude of the movement both standing and sitting. Usually, adults have acquired increasing rigidity from the end of skeletal maturity onwards. Therefore, the rotations of the trunk on the axis often lead to algias (pains) of the lumbar back muscles if done in the traditional free-body manner. Sometimes the goodwill of the instructor who warns against performing the exercise quickly and roughly is not respected due to the inability of the exerciser to get used to memorising so many things at once while performing the exercise. Therefore, this machine, which considerably reduces all these difficulties, allows even those who do not possess sufficient postural self-control and muscular control to work in absolute safety and comfort. The machine is pleasing in form and appearance. Simple to use, of considerable utility, safe and small in size, in short, a very interesting piece of equipment that should not be missing from any fitness centre.
Control movement to prevent injury and aid recovery. Even at the gym.
