The wrist expander is a small hand trainer. It allows you to increase the strength of the grip, and also promotes faster recovery of the hands after injuries and improves their mobility and blood circulation.
What to look for when choosing a wrist expander
When choosing a wrist expander, pay attention to its main characteristic - rigidity, which is expressed in kilograms. Stiffness refers to the force required to fully compress the machine. With this compression, the handles or two sides of the ring should touch each other. If the stiffness is not indicated on the instrument, most likely this is a low-quality product and there is no point in purchasing it.
When purchasing a spring expander, keep in mind that the most comfortable models have a special stiffness adjustment. They are especially good for novice athletes, since they allow you to set the most accessible figure first, and then check your achievements by periodically raising the bar.
Another criterion for choosing a hand trainer is its convenience. For example, a rubber ring can be carried with you at all times and squeezed in between activities, and a heavy steel unit will be appropriate for indoor training. Therefore, purchase a wrist expander considering where you intend to use it.
Types of wrist expander
A rubber expander is a hand trainer, which is a ring or small ball. The elasticity of such a simulator ranges from 20 to 50 kg, so it is more suitable for novice athletes.
Expanders-cocoons made of metal have a small rigidity from 2 to 25 kg. Their main advantage is that they, like rubber trainers, are convenient for people who have just started doing strength sports.
Another type of wrist resistance bands are spring trainers, which outwardly resemble pincers. Such a simulator consists of metal or plastic handles connected by a spring. The stiffness of the spring expander can range from 20 to 40 kg, they are used for warm-up and for full workouts.
Another option is units that are made entirely of steel. Their level of rigidity can reach 160 kg, they are usually used by professional bodybuilders.
The next category of hand trainers is gyroscopic models, which are usually small in size and have the shape of a ball that can be tightly wrapped in the palm of your hand and held with your fingers. The body of such an expander is made of transparent plastic, inside it is a gyroscope device. By spinning such a simulator in the palms, you can train the hand, fingers, wrists, shoulders, forearms and biceps with triceps.
