The Butterfly simulator allows isolated load the pectoral muscles... From the point of view of professional athletes, this is of great importance, since it makes it possible to create the visual depth and relief of a given muscle group. However, exercise is indispensable for amateurs and those who visit the gym to improve their health.
Muscle Groups Involved in Butterfly Exercise
Different accessory muscles can be used during the exercise, depending on the type of machine design. However, the main target group is the pectoralis major muscle. The main load during the execution of the movement falls directly on it.
It belongs to the large muscles of the human body. This muscle group is paired. This means that it consists of 2 symmetrically located parts that perform identical functions.
The main tasks of the pectoralis major muscle are:
- Bringing the raised arm to the midplane of the body.
- Lowering the arm straightened at the elbow.
The pectoralis major muscle is also involved in the breathing process. This function is due to the peculiarity of its attachment. The clavicular part originates from the large tubercles of the humerus. The sternum is attached to the cartilage of the first 6 ribs and the anterior surface of the sternum. The muscle has a fan-shaped triangular shape.
The pectoral muscles respond with an increase in volume to physical stimulation rather quickly. This group is prone to venous blood stasis during sports activities. Oxygen supply to the pectoralis major is carried out by the artery. Therefore, the effect of "pumping" is expressed quite clearly even with short loads.
Exercise Butterfly for the pectoral muscles includes the work of the anterior bundle of the deltoid and dentate muscles.
Also involved in bringing the hand to the midplane of the body:
- Small pectoral muscles.
- Latissimus dorsi. They are most intensively involved in work when working in the simulator with arms extended forward.
- Trapezium. A static load is placed on it to maintain the correct position of the back during the movement.
- Rotational arm cuff. It was used when performing the exercise with the upper limbs bent at the elbows. At the same time, the hands are directed upwards, and the shoulder is parallel to the floor.
Why are the pectoral muscles trained?
Training the chest muscles is due not only to the goal of increasing their volume, but also to a number of factors associated with maintaining human health:
| Correct posture | Many novice athletes try to do more exercises on the muscles of the back and shoulders to give the correct position of the spine. However, the pectorals are their antagonist muscles. Without developed and elastic chest muscles, it is impossible to form a healthy posture. |
| Respiratory function normalization | The development of chest muscles in combination with breathing exercises and diaphragm training can normalize the respiratory function of a person.This effect is due to the elimination of stoop and an increase in the length of the fibers of the pectoralis major and minor pectoral muscles, as well as other small auxiliary muscle groups. This facilitates the operation of the diaphragm. |
| Improving functionality | The pectoral muscles are one of the strongest and largest muscle groups in the human body. Consequently, directly or indirectly, they take part in the performance of most everyday tasks. |
| Improving breast shape | This is especially true for girls. Exercising the pectoral muscles will not increase the volume of the mammary glands. However, developed muscles are capable of giving an aesthetic shape and lifting the chest. |
| Strengthening the muscles of the shoulder girdle and back | When performing sports exercises on the chest muscles, a large number of stabilizer muscles and auxiliary muscle groups are involved in the work. This makes it possible to develop the muscles of the upper shoulder girdle harmoniously. |
Indications and contraindications for classes
Reduction of hands in the Butterfly simulator should not be performed with pectoral sprains and tears. It is advisable to refuse to perform this movement in the presence of pain in the shoulder and elbow joints.
Designed for athletes who set themselves the task of additional pumping of the pectoral muscles with blood. This allows you to increase the number of capillaries in the specified muscle group. That helps to improve the supply of nutrients to the pectoral muscles, and also accelerates the anabolic processes.
Technique for performing exercises on the Butterfly simulator
Butterfly exercise for the pectoral muscles is performed on a specialized simulator. Exact recommendations for performing the exercise depend on the design of the sports equipment.
The Butterfly trainer for pectoral muscles is a vertically oriented frame with blocks and weights. Blocks are needed to transfer effort from the hands of the athlete to the weight. The sports equipment is equipped with a bench with a vertical back and a horizontal saddle.
The handles of the simulator can be:
- Located at a short distance from the axis of rotation and equipped with soft pillows... To train on this equipment, the athlete's arms must be bent at the elbows. This puts additional stress on the rotator cuff and relieves stress on the back muscles.
- Articulated on a long arm... In the simulators of this design, the athlete brings his arms slightly bent at the elbow joint. This method of performing the movement removes the dynamic load from the deltoid muscles and includes the latissimus dorsi muscles.
Exercise preparation
The Pectoral Butterfly Exercise is an isolated movement.
To comply with the technique for its implementation, it is important to correctly configure the auxiliary equipment:
- Seat height adjustment. It should be positioned in such a way that the athlete has the opportunity to bring his arms in front of the chest, and not above or below the required level.
- Backrest angle adjustment... The vertical back support should be perpendicular to the floor. It is not allowed to perform the exercise on a simulator whose back is tilted even at a slight angle.
- Adjusting the Lever Length of the Handles... If the simulator has this function, then the length of the overhang is selected in such a way that the athlete has the opportunity to tightly press his pelvis and back against the vertical back of the bench of sports equipment.
Before starting each workout, you should take time to warm up. As a rule, hand reduction on the butterfly simulator is performed in the middle or at the end of the set, but if the training program begins with this exercise, then before doing it, you should thoroughly stretch the muscles of the upper body, warm up the elbow and shoulder joints.
Correct execution
The implementation of any sports movement begins with the acceptance of the starting position:
- Sit on the exercise machine bench in such a way that the feet rest securely on the floor surface. During the execution of hand information on the "butterfly" simulator, heel separation is not allowed.
- The shoulder blades should be pressed against the vertical back of the machine. During the movement, you should maintain a natural bend in the lumbar spine.
- Take the handles of the simulator with a closed free grip. At the same time, depending on the design of the sports equipment, the positions of the hands of the practitioner will differ from each other.
When working with a sports equipment in which the handles are equipped with pads, special attention should be paid to the position of the elbows. They should be tightly pressed, with the forearms perpendicular and the shoulders parallel to the plane of the floor.
When working with a simulator, the handles of which are movably fixed in the levers, you should also pay attention to the position of the elbows. With the limbs extended forward, the elbows should be slightly bent and slightly raised so that an imaginary straight line can be drawn through the student's hand.
After the student has taken the correct starting position, you can begin to perform information on the pectoral muscles.
During the execution of the movement, several recommendations should be followed:
- Reduction of the handles of the simulator should be carried out before they touch... Bringing the arms to the midline of the body should be performed by isometric contraction of the chest muscles. Involvement of biceps in work is not allowed. To do this, control the position of the elbows. During the exercise, the shoulders should be deployed. Rounding is not allowed.
- Breeding hands is carried out smoothly, without jerking... Do not put your hands too deeply behind the plane of the body. If limiters are provided in the simulator, then they should be set at the mark of 30-50 mm before crossing the indicated plane.
All movements during the exercise must be performed smoothly. For this, a 2 or 3 count is applied. In this case, the athlete performs a positive negative phase of movement in 2 or 3 seconds. It is necessary to remember the correct breathing technique. Inhalation is carried out on relaxation (arms spread), and exhalation is carried out on mixing.
Other techniques for making a butterfly at home
Not all gyms are equipped with a chest straightener. It is possible to replace this exercise with other athletic movements.
With dumbbells
The most common way to train the pectoral muscles in isolation is to flatten the arms while lying down with dumbbells. The exercise is performed on a horizontal bench or flat floor. The latter is preferred.
When performing flattening of hands with dumbbells on the floor, there is an insurmountable restriction that prevents the elbows from dropping below the plane of the body. This greatly reduces the risk of injury and makes the athletic movement anatomically correct.
With elastic
Reduction of hands with an elastic band can be performed both with the use of an additional support for the equipment, and without it... In the second case, the elastic is fixed behind the student's back at the level of the middle of the shoulder blades. The movement can be performed from a lying, sitting and standing position.
With elastic band
The pectoral butterfly exercise can be performed using long elastic bands.
In this case, the edges of the 2 tapes should be fixed on supports spaced apart from each other at a distance of 2-3 m. The free ends of the products must be securely fixed in the hands and, having taken a few steps forward from the plane of the supports, begin the exercise.
Useful Tips
When performing an athletic exercise, pay attention to the nuances and details. This will allow you to focus on the target muscle group and avoid common mistakes.
When performing the Butterfly exercise, the following recommendations are useful for application:
- Reducing the arms in the simulator is an auxiliary movement. It should be performed after basic barbell presses.
- Breeding hands is performed 1.5-2 times longer than mixing.
- Jerks and inertia during the exercise are not allowed. Movements should be smooth and controlled.
- Shoulders should be avoided when bringing the arms together. This violation of the technique shifts the emphasis of the load on the trapezius muscles of the back.
The Butterfly Reduction is an effective exercise for developing chest muscles. It can fit into any basic training program and is an isolated movement.
This determines the number of repetitions performed in each approach. This value should be within 12-15 repetitions. The number of approaches should not exceed 5.
