Exercise is good for health, but also need to have the right way, if the exercise method is not appropriate, not only can not play a role in strengthening the body, but will be harmful to the body. U.S. “Prevention” magazine recently published an article, pointing out that several easy to make mistakes in the way of exercise. 1, standing and bending over to reach the toes Many people like to bend over to reach the toes, that can effectively stretch the Achilles tendon. In fact, this exercise method will make the whole body gravity are concentrated in the back, the back caused a lot of pressure, so that the intervertebral disc overload pressure. You can use a sitting position, bend down enough to reach the toes, relatively more secure. 2, lunge leg press step is too small This will cause greater pressure on the bent knee and tendon muscles, and over time even get arthritis. The correct way to lunge and press the leg is to take a big step, and the distance between the front heel and the back knee should be about 60 centimeters. 3, sit-ups do too many people do sit-ups to reduce abdominal fat, in fact, this exercise effect is not obvious, do too much but easy to damage the back muscles. Therefore, sit-ups should not be excessive, and be sure to bend the knees. 4, push-ups arms away from too far This is not only bad exercise, but also cause shoulder pressure injury. The correct action of the push-ups is to let the wrists be directly below the shoulders. 5, outward stretching thighs when the knee is bent inward, the soles of the feet outward when it is easier to let themselves get hurt. The correct and safer way is to bend the knee outward, so that the sole of the foot to the other thigh to the inside of the force, so that the two legs in the shape of the number “4”. 6, lifting dumbbells when the neck forward This is actually a kind of weight exercise unconscious behavior, but always this will damage the neck muscles. A clever solution is to work out consciously eyes staring ahead of a place to see, and deliberately to tighten the jaw, so that you can avoid the neck to explore the front. 8, side lifting dumbbells lifted too high Do not think that side lifting the higher the better the effect, so that the effect of exercise is not outstanding, but will damage the shoulder muscles. A study shows that, in fact, the side lifting dumbbells as long as lifted to the position of the hips can be, the effect and lifting to the position of the shoulder is almost the same. 9, the side bench press crotch crotch will reduce the body’s gravity, a lot of people’s bodies held up unconsciously after the crotch, this will reduce the effect of exercise. Should let the body from the head to the feet to maintain a straight diagonal line, always caution yourself not to lift the crotch. The correct action for 20 seconds is equivalent to the effect of the wrong action for more than 1 minute.
