Expander – the small device which allows to train hands, muscles of the forearm and the wrist. There are models by means of which it is possible to train only one hand, is also such which are suitable for occupation with both hands. It is also possible to use at the same time two expanders.
What expanders happen
From what expander at you, in many respects depends also the training with it. There are two main types of expanders which it is possible to call classical.
The first is the round ring from rubber, the most known kind of the exercise machine. Material of the expander springs, interfering thereby with any interaction with it. The training essence also consists in it.
There are also expanders to two handles between which the elastic springing design is located. Such expander needs to be stretched. There is one more type of the expander rather new is the rubber ball or the ball. Too it is necessary to squeeze it as well as the ring, but difference that it is possible to do it by two hands at the same time. Such expander trains breast muscles. There are also other models of expanders, but them it is possible to call everything more likely exotic as these versions mean everyone the way of the training. For example, there are expanders in the form of the wheel. More difficult devices meet electronic counters. Convenience of expanders in their sizes: it is easy to take them anywhere, in the business trip or in the travel, for work or on walk. Some train hands the expander to think and focus on some things.
How to train with the expander
The training with the expander means one simple exercise: tightening or unclamping of the palm in which you hold this subject. Do so until the hand isn't tired finally. Then have a rest several minutes (at this time it is possible to train other hand) and make one more approach. At first the hand will be quickly tired, but gradually bring the number of approaches on each hand approximately to ten. When it begins to come easily to you, complicate trainings: during the break between approaches don't relax the hand, and squeeze in it the expander. If you have the expander which needs to be stretched, then all provided recommendations in the same measure treat also it. That trainings were effective, it is necessary to choose the correct expander. The exercise machine suitable you has two properties: he ideally lays down in the palm and has the necessary rigidity. The second parameter deserves special attention. The rigidity shouldn't be such that you easily coped with the expander, squeezing it without fatigue several dozen times from the first day of trainings. It is necessary that you had to use the serious efforts. It isn't recommended to buy the expander with the metal spring in the middle as sooner or later the skin fold can get there, and you are traumatized that considerably will cool your interest in trainings.
