Balance discs

Car Rim

— a device in the form of a characteristic round (disk-shaped) pillow filled with air. The disk is inflated to such an extent that it noticeably (but not to the floor itself) sags under the user's body. Due to this, an unstable surface is created, and numerous muscles must be used to maintain balance on it. In addition, one side of the disk is usually complemented by a set of spikes or other protrusions that create a massage effect.

The balancing discs can be used both standing and sitting; if you wish, you can even engage with such a projectile while sitting at a table in the workplace. In general, such a projectile helps to train coordination and the vestibular apparatus, strengthen the main muscles of the body, as well as correct posture and prevent problems with it. There are different disc exercises designed to develop different skills and muscle groups; these nuances, as well as contraindications for use (they also exist) should be clarified in special sources.

Also note that some manufacturers and sellers call balancing discs “pillows”. This is not entirely true — the pillow is still different in shape and application; see the relevant paragraph for more details.
