Rubber expander can significantly improve the shape of the body and provide excellent training. This is an excellent tool to strengthen muscles and keep them in good shape during a period of forced downtime. Such a simulator is often used by athletes and bodybuilders during aerobic and weight training. It is lightweight, takes up little space and fits easily in a bag. With frequent business trips or a trip on vacation, you can take it with you on the road and train anywhere.
Rubber expander has several advantages:
- This is a universal practical simulator (suitable for men and women);
- ease of use;
- inexpensive cost;
- available in every gym, fitness center, sports store;
- the possibility of compiling an individual program for video recordings;
- load change depending on the strength of the training athlete.
The stretching expander is based on the principle of counteracting its elastic part to movement. To bring it into action, tensile efforts are required. Due to this, the load and stretching of several muscle groups are provided. 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 develop the strength and endurance of a person.
The rubber expander allows you to perform gymnastic exercises and aerobic elements in the gym and in the pool. Having strengthened it around the hips and behind the wall (pool or Swedish), you can perform a number of exercises, which at a good pace are an excellent training for the cardiovascular system:
- jogging (in water using floating equipment, fins);
- walking forward - backward (you can raise your knees high);
- swimming in 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. Shortened tape shock absorber.
4. Shock absorber with fixation for the feet.
5. Terra bow.
At home, it is enough to hook the rubber expander on the door and perform the following exercises:
- for the hands and muscles of the shoulder girdle - pulling up the shock absorber, bending and lifting the arms to the sides;
- for legs - flexion of the knees lying down, squats;
- for the press - twisting on the block, tilting to the sides ;
- for buttocks and hips - leg presses;
- for the back - traction in a sitting position;
- for breasts - arms crossed.
The skier’s expander is a long elastic cord made of rubber (braided) with handles. Its principle of action is to unclench and squeeze a projectile. It is designed to develop the dynamics of the hands in motion and is very effective for training the forearms, hands. Systematic training with such a simulator develops the target muscles, improves the functioning of the body and arms, gives the relief shape of the upper body.
