Chinese name: mbth, elastic belt: Elastic suspender material: natural latex function: improve muscle strength and body flexibility. Principle: Elastic resistance changes with elongation. Usage: resistance, lower abdominal sit-ups, etc. 1. What is elastic belt? Elastic belt is a small physical training tool, which is easy to carry, simple to use and very effective. /kloc-More than 0/00 years ago, elastic belt's resistance training tools were used in the field of fitness, mainly for male strength training and female self-cultivation programs. And is widely used in the field of rehabilitation training. Elastic belt is often used as a fitness training tool at home or on business trips. It can cooperate with the rhythm of music and become an aerobic training that can quickly cultivate self-cultivation, strengthen cardiopulmonary function and improve posture. If the trainer refers to the professional elastic belt training video, the training effect will be more significant. 2. The source of resistance of elastic belt mainly varies according to its elongation. Elastic belt elastic resistance training is a very special resistance training. When using elastic belt training, users can train most muscles in almost any position and posture, which is more convenient and effective. The resistance of elastic belt is calculated in kilograms according to its elongation at relative rest. When training in elastic belt, you can evaluate the resistance according to the change of length, and you can also choose the appropriate elastic belt length according to your own situation. 3. The advantage of elastic belt training is that it is easy to carry and can be trained at any time. Lightweight, it is a training tool that can be carried around. It has nothing to do with gravity and can rotate freely. Resistance comes from elastic belt's elongation rather than gravity, so training is more free and changeable. No inertia, no motivation, no leverage. Because the resistance provided has nothing to do with gravity, you can't use strength during training, and the training effect is better. It can imitate daily movements and improve functionality. Elastic belt training can be performed in any posture and any plane, which is more functional. 4. Matters needing attention in elastic belt training. Improper use may lead to injury. It is recommended to consult a professional or refer to a professional elastic belt training video before use. B. Before use, check whether there are gaps, cracks or pinholes in elastic belt. C. replace it regularly. If it is used frequently,/kloc-0 needs to be replaced after 2 months. D. When using, don't wear jewelry or keep long nails, so as not to cut elastic belt. People who are allergic to rubber should use rubber-free elastic belts. F try not to do training in front of your eyes to prevent injury. G. don't overstretch the elastic band. In general, the elongation should not exceed three times the original length. H. Check the connection and ensure that the whole belt training is elastic. 5. elastic belt resistance training can achieve three different training effects: ① increase muscle strength (increased strength makes movements easier); ② Increase muscle girth (muscle fibers become thicker and girth increases); ③ Increase muscle endurance (repeat the action many times, but don't feel tired). Before training, you should first consider your training objectives. Different training purposes and methods can produce different * * * on muscles and achieve training results. For example, in order to thicken muscle fibers and increase muscle circumference, bodybuilders in the market will adopt a training program with high resistance and few times; On the contrary, in order to reduce fat and tighten loose muscles through training, women will adopt a low-resistance and repeated training method. 6, elastic belt training posture essentials elastic belt training, if you don't know the action essentials, plus your own muscle imbalance, you will often keep your body in a bad posture (such as holding your chest out or collapsing). If you train with bad posture for a long time, it will not only reduce the training effect and fail to achieve the original training purpose, but also strain your muscles and increase the chance of injury. Trainers can refer to professional elastic belt training videos for training. 1) In daily life, such as when using a computer or watching TV, it is easy for us to hold our heads forward. If you keep this posture for a long time in elastic belt, it will change the physiological curvature of the cervical spine, make the surrounding muscles stiff, and make the cervical spine degenerate in advance. Therefore, when training in elastic belt, we should pay attention to the slight retraction of the jaw, and don't lean forward. 2) During the training of sinking shoulders and chest, the shoulders should relax, sink, contract and chest. Because every joint of the body has a most suitable movement position, if the position is not good, the pressure and wear of the joints will increase during the exercise, which will eventually lead to injury. So when training in elastic belt, try to sink your shoulders and take them back. 3) We need to pay attention to good posture in training. During training, keep the pelvis in a neutral position (don't lean forward or backward), and at the same time tighten the abdomen slightly inward to increase the stability of the trunk and prevent injury. 4) When you stand on tiptoe, your knees should bend slightly, not too straight. This is because the excessive extension of the knee will make the ligaments and soft tissues at the back of the knee longer and looser, leading to unstable joints and easy injuries. In addition, when standing training, the knee joint should point to the toes and not buckle inward to prevent damage to the medial ligament.
