First of all, he is in his early to mid 30s. I'm in the design field, so I work on the computer for more than 6 hours a day, so my shoulders are hunched and I get a lot of headaches. Since my shoulders look hunched, my trapezius muscles look convex and my self-esteem drops... (I can't wear thin t-shirts in the summer hahahaha) I know about botox for trapezius muscles. As I was looking at it , I saw an advertisement for it and I bought it because the price was cheaper than I thought, although I wasn't sure about its effectiveness. Looking at the composition, it may be effective for the trapezius muscle, but it doesn't seem to be effective for my curved back. Anyway, the goal is to reduce the trapezius muscle, so you have to believe it to get your money's worth! 20 days of 10 minutes before going to bed. It may not have the amazing effect that people say about Botox, but the trapezius muscle has gone down a lot compared to before haha. (You can see the difference when you look in the mirror.) For the shoulder bending, I followed a YouTube stretching video and used the product together. I was concerned about the pain and side effects of Botox, but since it is somewhat effective, I am thinking of stretching and using it consistently! The advertisement I saw is below, I recommend it to anyone who is thinking about it! https://blog.naver.com/goodsonbasket/223182616092
