Uniqueness lies in their form and method of use. The simulators themselves only create conditions for performing basic movements on them, but taking into account safety requirements. Thanks to its shape, the ankle development machine helps place the foot so that the toes are in a state of passive extension throughout the entire movement - this will allow the plantar aponeurosis to be stretched, which will make the arch a little higher, that is, the ballet lift will be more pronounced. By maintaining such an arch when performing movements in the ankle joint, a habit is formed. The foot will change because the conditions for change have been made, and not because it is forcibly broken - this is health saving.
The stretching machine, due to its shape, helps to use short levers for stretching - this solves the eternal problem of uneven splits when the pelvis turns behind an unstretched muscle.
This happens because the muscle is not an elastic band and does not stretch. You can safely stretch a muscle using reflexes. By performing simple exercises on the machine, greater brain power is used, which will make the stretching process more effective.
