How to do barbell squat? Barbell squat? Belong to? Squat with weight? . Barbell squat is one of the basic movements to develop lower limb muscles. However, some beginners will feel uncomfortable after practicing squat, such as back pain, tenderness and redness behind the neck, even if the shoulder and neck are padded with sponge. Why is this happening? The main reason is incorrect movements, especially improper placement of barbells. Improper and unsafe barbell placement will not only distract the attention of practice, affect the effect, but also easily cause sports injuries. Statistics show that the barbell slipping off, or tilting, swinging and shaking left and right when squatting, is an important cause of low back pain. Because the barbell is heavy, it is difficult to control when squatting.

Action process

Put the barbell behind your neck, grab the barbell with both hands, keep your body straight, look straight ahead, and your feet are shoulder width apart. Bend your knees and squat slowly until your thighs are parallel to the ground or slightly below your knees. After holding, the quadriceps femoris will contract hard, kick and stretch the knee until it recovers. Action rhythm: squat for 2 -3 seconds, stay still 1-2 seconds, squat for 2 seconds.

Squat is a double joint action of stretching hip and knee, which can be divided into three stages: preparation posture, squat and squat.

1. Stand by. Beginners must first determine the exact location of barbell placement. Hold your head high and your back straight, but don't overstretch. After the scapula contracts, put the bar on the raised trapezius and deltoid muscles to adjust the balance. The weight of barbell is shared by four points, in which trapezius muscle bears most of the weight, and there is no need to pad sponge and other cushions. Even if the body is thin, the deltoid and trapezius muscles are weak, can they be completely? Eat heavy? And there will be no discomfort such as pain. Raise your arms sideways and hold the crossbar with both hands to maintain stability.

The heel is padded with a board or barbell about 3 cm thick. Because the total center of gravity of the human body and barbell moves backward after the shoulder is loaded, but the back can't lean forward. Only by raising the heel to passively move the center of gravity forward can we restore to a stable supporting state. The regained balance can also increase the force on quadriceps femoris when squatting. After the barbell is lifted, adjust the position of your feet. The distance between feet is generally shoulder width, and the adductor muscle is too stressed and developed, which is not conducive to beauty and life. Your feet should be in a natural position with an angle of 30 to 45 degrees. The barbell placed on the cervical spine will cause pain, and it will also form a chest bow and waist movement, strengthen the tension of the back muscles, straighten the limbs and straighten the back.

Step two, squat. When you are ready, take a deep breath, bend your knees slowly and control your squat. When squatting, the knee joint direction is the same as the toe direction, and the thigh is parallel to the ground or slightly lower than the knee. If the hip falls to the ankle joint, the squat is too low and unnecessary, which is easy to cause joint injuries such as knees and ankles. The speed of squatting should not be too fast. We should master the rhythm, at least the speed of squatting should not be faster than the speed of squatting. Because there is an obvious time effect after muscle stretching, the longer the time, the more muscle strength decreases and the less muscle strength decreases.

Therefore, the weight that a weightlifter can lift immediately after squatting may not be lifted after a long pause after squatting. The reason is that he immediately squatted down and stretched with gluteal muscles and quadriceps femoris, which increased muscle elasticity and enhanced muscle strength. The requirements of bodybuilding are different. Squat down to a minimum of 1-2 seconds, and then squat down again. Although the squat weight is smaller, the actual stress on the lower limb muscles has not decreased, which is relatively safer.

Squat. The most valuable squat exercise is the squat stage, where attention is focused on the legs and all the legs exhale forcefully at the same time. Hold your head up. Imagine kicking your legs hard and pushing your head up, instead of lifting your hips first and then straightening your waist. During the whole squat process, the center of gravity should be stable and the feet should not move.
