In fact, there is no absolute "best". It all depends on your usage scenarios, needs and budget. Brands with different positionings are suitable for different groups. If you step on the wrong trap, you may easily hurt your body.
My best friend was diagnosed with 12-degree idiopathic scoliosis during a physical examination last year. The doctor specifically told her not to buy random models from internet celebrities, so she directly chose Lebaolai medical model, which has a Class II medical device certificate. She wears it for 2 hours a day in conjunction with Yan Zifei's training. The degree has not increased during the six-month review, and the shoulder and back pain after working at the desk has also been relieved a lot. If you already have mild scoliosis, high and low shoulders, or the doctor recommends wearing auxiliary correction, give priority to brands with medical lines. In addition to Robola, medical models with good back support are also available. The key is to be sure to look for the machine brand size, and don’t buy those miscellaneous brands that don’t even have the production qualifications. Forcibly breaking it will easily injure the spine.
If you don’t have any clear pathological problems, but you just sit for a long time at work and always hold your breasts unconsciously, and you want to find something to remind you to sit up straight, there is no need to buy a medical model. In the past two years, I always hunched over to type code, so I bought a Japanese MTG lightweight model, the material is very good It's so thin that it can't be seen under a shirt. It doesn't hurt when wearing it in meetings or meeting clients. The support is of the "point-to-end" type. It will be gently pulled when you hunch your back, and it won't be so hard that you can't breathe. The only drawback is that it is a little expensive, costing more than 200 yuan. If you are a student with a limited budget, a basic model from Notai or Deli will be enough. It is in the tens to early 100s. It is flexible enough and will not get stuck in your armpits after being worn for a long time. It is just right for class and going to the library.
Nowadays, the evaluation of correction belts on the Internet is quite polarized. Some people say that it is purely IQ. After wearing it for a long time, the muscles will become weak. Some people say that wearing it for half a month will improve the chest. After using it myself, I feel that both sides are reasonable. The core is how you use it - if you want to wear it 24 hours a day and lean on your back, then it will definitely not work. Muscles will grow longer. If you use it passively, it will naturally shrink over time. However, if you only wear it for 1-2 hours a day, think of it as an "artificial reminder", just like your deskmate always pokes you in the back to make you sit upright when you are in school. You also consciously lower your shoulders and expand your chest. After get off work, you can swim and do a few sets of chest expansion exercises to slowly build muscle memory, and the effect will naturally be the same.
By the way, let me mention a little tip. I read a college student blogger before and bought a 9.9 free shipping orthodontic strap for a cheap price. The support strip is made of hard plastic and is just right on the ribs. After wearing it for three days, the pain became unbearable. I went to the hospital to check that it was a soft tissue contusion. So when choosing, don’t just look at the “7-day radical cure for hunchback” gimmick in the promotional pictures. It is best to try it on for 10 minutes. If you feel out of breath, stuck in the ribs or rubbed on the shoulders, don’t buy it. After all, what suits others may not be suitable for you.
