What are the benefits of straightening your legs? With the development of life, more and more people begin to exercise through fitness. Many people will straighten their legs, that is, keep their legs upright when pulling hard. What are the benefits of straightening your legs? Read this article to find the answer.

What are the advantages of pulling straight legs hard? 1 1, strengthen leg strength.

Straight leg hard pulling can fully exercise the hamstring muscles of the legs and effectively enhance the strength of the legs.

The straight leg will not bend the knee during the movement, and the leg will almost remain upright. Therefore, the hamstring muscle can be stretched to the greatest extent and fully stimulated.

In addition, quadriceps femoris and hamstring are the active muscles in leg bending and hard pulling, while hamstring is the only active muscle in straight leg hard pulling. Therefore, hamstring muscles with straight legs will participate in more exertion and get better exercise.

2, strengthen the back muscles

Although the back muscle is not used as the active muscle in the hard pull, the straight leg hard pull is better for the leg exercise, but its participation is not less than that of the leg. Straight leg hard drawing is a great strength training. Back muscles need to keep the core stable, ensure the rigidity of the upper body and transmit strength, which plays a very important role and requires high back strength. Therefore, straight leg hard pull training can also exercise the erector spinae of the back, especially the lower back, thus strengthening the back, improving the core strength, helping to maintain the stability of the spine and making the waist stronger.

Step 3 exercise hip muscles

In straight leg hard pull, leg muscles are the active muscles of hard pull, and gluteus maximus is the cooperative muscles of hard pull. Hip muscles are the most important exercise parts besides back and leg muscles. Therefore, through the straight leg hard pull training, you can exercise the hip muscles well, make the hip muscles firm, elastic and linear, and keep you in better shape.

4, enhance grip strength

No matter what kind of hard pull, it is pulled up by the hand that grabs the heavy object. If the hand muscles are too weak and the grip strength is not enough, then even if the strength of the back and legs is strong, the action cannot be completed. In order to solve the problem of insufficient grip strength, trainers often use power-assisted belts to assist training. However, the high demand for grip strength by hard pulling in turn exercises the hand muscles and enhances the grip strength.

5, strengthen the arm muscles

In order to pull heavy objects with straight legs, in addition to sufficient grip strength, necessary arm strength is also indispensable. In the process of pulling down the straight leg, the arm muscles are always in a state of contraction, and the lifting of the barbell is controlled by force, especially the stimulation to the forearm muscles. Therefore, hard pulling with straight legs also helps to enhance arm strength.

6. Strengthen the shoulders and trapezius muscles.

The deltoid and trapezius muscles of the shoulder are not the main exercise parts of straight leg hard pulling, but they will also participate in training and get some stimulation when hard pulling. So pulling hard with straight legs can also help strengthen the strength of deltoid and trapezius muscles.

7, improve the overall strength of the body.

Like all hard pulling, straight leg hard pulling is also a heavy compound action. During hard pull training, many muscles involved in the body, including the main leg, back, buttocks, palms, arms, core muscles, shoulders, trapezius muscles, etc., will be stimulated. Therefore, through straight leg hard pull training, one's overall strength can be effectively improved. This is not available in other sports.

8. Enhance physical coordination.

Hard pulling is a compound action. In the process of movement, many joints and muscle groups of the body need to cooperate with each other to complete the movement. Therefore, through hard pull training, we should not only exercise a certain part of the body alone, but also coordinate all parts, which also enhances the coordination ability of the body and makes the body more flexible.

What are the advantages of pulling straight legs hard? 2 which part of the body does the straight leg pull exercise?

1, leg muscles

No matter what kind of hard pull, the muscles of the leg are all the starting muscles, so the leg is one of the most important exercise parts of hard pull. However, the straight leg can bend forward without bending the knee, and the whole leg remains straight. Compared with bending leg hard pull, straight leg hard pull can stretch hamstring muscle to the greatest extent, thus increasing the stimulation to hamstring muscle. Therefore, hard pulling with straight legs can exercise leg muscles, especially hamstring muscles at the back of thighs.

2. Back muscles

Although the leg is the starting muscle, the back muscle plays no less important role in hard pulling than the leg. Back muscles play a role in maintaining body stability, ensuring upper body rigidity and transmitting strength during the whole straight leg hard pulling action. In the field of fitness, most people take hard pulling as the main exercise training of the back. Therefore, the straight leg hard pull is also very effective for the back erector spinae exercise, especially for the lower back and even the main back training. Of course, for upper back muscles such as latissimus dorsi, hard pulling also has a good training effect.

3. Arm muscles

Hard pulling, like squatting, requires hip flexion and extension. Straight leg hard pulling is no exception. The gluteus maximus works as a cooperative muscle when the straight leg is pulled hard. Other hip muscles are also the most stable participants. Therefore, hip muscles and other related muscles are the most important exercise parts besides leg and back muscles.

4. Arm muscles

No matter what kind of hard pull, it is the action of pulling up heavy objects by physical strength. It is natural to rely on the strength of the arm to pull up heavy objects. During the whole straight leg hard pulling exercise, the lean muscles are always in a state of contraction and constantly exerting force. In particular, the forearm muscles need the palm to grasp the barbell, and the muscle stimulation is more obvious. Therefore, hard pulling with straight legs can also fully exercise arm muscles.

5, palm muscles

No matter how heavy the barbell is, it needs to be pulled up by hand. And if the palm muscles are not strong and the grip strength is not enough, even if the strength of other parts of the body is strong, it is difficult to complete the hard pull action. The requirement of straight leg hard pulling on grip strength, in turn, also exercised grip strength and enhanced the strength of palm muscles.

6. Abdominal muscles

In the hard pulling of straight legs, the core parts such as abdominal muscles are needed to maintain the stability of the body, ensure the rigidity of the upper body and transmit power. Therefore, in the training process of straight leg hard pulling, abdominal muscles will also get a certain training effect.

7. Shoulder and trapezius muscles

In the process of hard straightening the leg, the deltoid and trapezius muscles of the shoulder will also participate in it and get some stimulation. Therefore, insisting on hard pull training can also make the trainer have broad and strong shoulders and developed trapezius muscles.
