Shoulder expander - a manual simulator for maintaining muscle tone, performing exercises with a load on the dorsal and pectoral muscles. A practical device allows you to make charging more efficient and increase the load when performing a warm-up.
Regular exercises with a shoulder expander for men and women make it possible to completely refuse to visit the gym. Classes with the device contribute to a thorough study of the muscles, even if the growth of the latter is not as progressive as when training in functional simulators in fitness centers.
Benefits
Among the main advantages of the shoulder expanders, it is worth noting the following:
- The equipment is ideal for training at home.
- Most models are compact, lightweight.
- Exercises with the device make it possible to exert isolated loads on small, previously unused muscle groups.
- The device can be used by both men and women.
- Using the shoulder expander, you can increase the load when performing any habitual exercise.
- Intensive training using a projectile contributes to the rapid burning of fats, obtaining a beautiful body relief.
Shoulder spring expander
Structurally, the device consists of two handles connected by springs. Loads are regulated here by replacing and installing stretch elements with increased or reduced stiffness. Such shoulder expanders are distinguished not only according to the number of springs, but also the materials from which they are made.
The use of equipment of this category contributes to the development of the entire shoulder girdle, the provision of increased loads on the pectoral muscles, and a high-quality study of the biceps and triceps.
Shoulder rubber expander
Such models are universal. They find the broadest application when performing exercises for training the muscles of the buttocks and thighs, the entire lower and upper body. The rubber brachial expander may contain handles or cuffs that are fixed on the legs with Velcro.
The stiffness level of such inventory is determined according to the color of the rubber:
- Yellow shades have minimal resistance and therefore are an ideal solution for beginner athletes, people who prefer light workouts at home.
- Green rubber shoulder expander - suitable for more trained athletes. With its help, you can exert medium load on the muscles.
- To stretch the red fixtures have to make remarkable efforts. Therefore, their operation is to the liking of trained athletes, true fitness fans and lovers of strength training in gyms.
- Black and blue expanders have the highest possible resistance. Used by professional athletes who need to provide increased, accentuated loads on individual muscle groups.
How to choose a shoulder expander?
How to choose a good shoulder expander for effective training? Users, for whom the workmanship and long service life are in the first place, should focus on the products of famous manufacturers. Cheap models made in China are often torn during operation, which can lead to painful blows. Be that as it may, reputable companies always guarantee compliance of the real qualities of products with the declared properties.
The main criterion for choosing a shoulder expander is the level of resistance. During operation, the weakest products have to overcome loads of up to 5 kg. Expanders with maximum resistance are forced to apply a force of up to 100 kg. Often the level of stiffness is indicated on the inventory and is indicated in numbers:
- “1” - low resistance;
- "2" - average rigidity;
- “3” is a strong resistance.
Before buying, it is advisable to test the shoulder expander. It is enough to stretch the device in separate directions, applying various forces. If preference is given to a rubber expander, it is necessary to inspect the product for microcracks and tension in the form of white stripes on the surface of the material.
It is advisable to dwell on models with rough handles, the shape of which is most convenient for holding. In this case, you can avoid accidental slipping of the simulator from wet hands and getting injured.
