Max. user weight
The maximum mass that the shell of a gymnastic ball is able to withstand. The maximum user weight is closely related to the maximum load on the inflatable bladder. In the process of jumping and swinging, a user weighing 100 kg can create almost twice as much load on the fitball, for this reason, in parallel with the weight limit, manufacturers of gymnastic balls often indicate the value of the maximum load.
Equipment
—
Anti-break (ABS) — a safety system that prevents a sharp break of the ball as a result of a puncture of the inflatable chamber. Implemented by Anti-Burst System (ABS) technology. Some manufacturers label anti-burst fitballs with the abbreviation BRQ (Burst Resistant Quality). In essence, ABS and BRQ technologies are completely identical. Anti-explosion involves the use of a dense inflatable chamber. The structure of such a ball endures even high loads, and if a puncture occurs, the inflatable chamber will not be torn by the pressure of the outgoing air — the ball will simply slowly deflate. In this case, there will not even be a deafening pop, as when a balloon is punctured.

Spikes provide a massage effect. Fitballs with spikes are used for relaxation, treatment and prevention of various ailments. Spikes can be both pronounced and partially pronounced.

Pump. The gymnastic ball is in addition completed with the pump. As a pump, a foot-operated air pump is most often used, which is connected to the inflatable chamber with an extension hose. But the pump can be manual. Typically, a manual air pump does not use a flexible extension hose.

Expanders are elastic extensions with a handle for a comfortable grip. The spring properties of the expander allow you to create an additional load on various muscle gr
...oups, so you can significantly expand the scope of the gymnastic ball. Most often, the fitball is equipped with a pair of expanders. For their secure fixation, lugs built into the inflatable chamber are often used, but in some cases, expanders can also use an external belt for fixation.Diameter
The diameter of the fitball largely determines the age category of users. Gymnastic balls for adults have a diameter of 50-80 cm, while for children — about 30-50 cm.
Regarding medicine balls, the diameter of the vast majority of balls is in the range of 20-35 cm. Some manufacturers of medicine balls tie the diameter to the mass. With an increase in the weight of a sports equipment, the diameter may also increase. Additionally, the girth of the medicine ball may depend on the specific purpose of the ball. Projectiles for throws, bench press and weighting during warm-up often differ from each other in diameter.
