Rubber Expander - a practical cushioning machine
Rubber expander allows you to significantly improveshape the body and provide an excellent workout. This is an excellent tool for strengthening the muscles and supporting them in tone during periods of forced downtime. Such a simulator is often used by athletes and bodybuilders during aerobic and power loads. It is lightweight, takes up little space and easily fits in the bag. With frequent business trips or a vacation trip, you can take it with you on the road and train anywhere.
The rubber expander has several advantages:
- It is a universal practical simulator (suitable for men and women);
- ease of use;
- inexpensive cost;
- is available in every gym, fitness center, sports shop;
- the possibility of compiling an individual program on video records;
- changing the load depending on the strength of the trainee.
Expander stretch is based on the principlecounteraction of its elastic part to movement. To actuate it, tensile forces are required. This ensures the loading and stretching of several muscle groups. The use of such a simulator allows you to reduce or increase physical activity. Reducing the length of the rubber shock absorber, increasing its elasticity develops the strength and endurance of a person.
The rubber expander allows you to performGymnastic exercises and elements of aerobics in the gym and in the pool. Having strengthened it around the hips and behind the wall (pool or Swedish), it is possible to perform a series of exercises, which at a good pace are an excellent training of the cardiovascular system:
- running with tension (in water using floating means, fin);
- walking forward - back (you can raise your knees high);
- swimming with different styles;
- in classical aerobics - some elements of choreography.
Modern industry produces several types of rubber shock absorbers. Depending on the elastic qualities, the following types of expanders are distinguished:
1. Elastic bandages:
- yellow - very light;
- light green - light;
- pink - medium;
- violet - elastic;
- Red - very elastic.
2. Rubber harness with handles.
3. The shortened tape shock-absorber.
4. Shock absorber with fixation for feet.
5. Terra-bow.
At home, the rubber expander is enough to hook on the door and perform the following exercises:
- for the arms and muscles of the shoulder girdle - tightening the shock absorber, bending and raising the arms to the sides;
- for legs - bending knees lying, squats;
- for the press - twisting on the block, tilting to the sides;
- for the buttocks and thighs - presses by the feet;
- for the back - traction in the sitting position;
- for the chest - crossing hands.
The skier's expander is a long elastic cord made ofrubber (in braided) with handles. Its principle of operation is to unclamp and squeeze the projectile. It is designed to develop the dynamics of the hands in motion and is very effective for training forearms, hands. Systematic training with such a simulator develops the target muscles, improves the work of the body and hands, gives the relief outlines of the upper part of the trunk.
