Expanders for the hand are a group of sports simulators, the exercises on which are based on elastic deformations. A group or individual elastic elements that provide loads when resisting all movements can be rubbery, springy, and they can also be made from various elastic materials. Exercises for the hands with the expander are most often directed to the development of small muscle groups, for example, for the chest tightening exercise . These physical loads belong to the group of so-called isolating (isolated) trainings.
Types of expander - simulators for the hands and other parts of the body
The main types of simulators include the following:
- Carpal expander, created specifically for the development of all the muscles of the forearm;
- The simulator, created in the form of a conventional rope made of rubber materials;
- breast expanders. Models consist of two handles, which are connected together by a set of bundles and springs. Due to the change in the number of bundles and springs, the load level can be adjusted. There are also models in which there are no individual handles, they are made of the same elastic materials;
- espanders for skiers;
- expander butterfly - it is necessary for training the muscles of the thigh;
- separate types of expanders, created for regular bending of joints in elbows and hands.
Varieties and benefits of hand expanders
Simulators for the hand (the expander) there is a large and varied amount. Each device is different in form and material execution. The most common model is rubber ring expander "Ring" , which, when compressed, has a variety of resistance. This degree is measured in weight (kilograms) - 15-65 kg. Constant employment with an expander for the hands strengthens the brushes, improves blood circulation, and also the condition of the skin on the hands.
Using a special ball expander , a spring or adjustable simulator, you will not torment yourself with the question of how to pump up your hands with an expander. As this kind of simulator makes the exercises simple and convenient. Universal and compact models can always be used, regardless of the place or time.
In addition to rubber models, there are also metal expanders . From conventional simulators they are distinguished by their high strength and lifetime guarantee. In addition, models have a wider range of resistance during compression - from 25 to 165 kg. The only drawback of such simulators is a relatively high price in comparison with the usual models.
Another unlike and interesting view is the gyroscopic simulator , which differs from the generally accepted models. In such unique expanders, the working elements are gyroscopes that are designed to form the muscles of the shoulder and other arm muscles, to treat or prevent tunnel syndrome, and to restore any connective tissue. When the devices rotate, the multicolored LED backlight turns on. In order for the simulator to be securely fixed in the hand, a belt was created from a special kind of non-slip rubber, which is hypoallergenic. Given all of the above, it may seem that this model is very difficult to use, but in fact the principle of working with it is very simple, it is just necessary to have a preliminary consultation with a specialist.
How to pump up your hands with an expander? All exercises are simple and useful for people with joint diseases, poor peripheral circulation, hypertension, insomnia . Also, such physical exertion is simply necessary for people who are engaged in mental work, schoolchildren and students. Athletes are encouraged to gradually and regularly increase the load on the simulator, using a large resistance expander.
