In fact, according to my sports experience of about 20 years, household use is: generally speaking, plastic coating is enough. Because you only use it to exercise, not wear it around your neck every day. To be so beautiful is simply "flashy". Most people don't like packaging, just because its outer layer is easy to break. But in fact, paying more attention to maintenance will not. Electroplating is generally purchased in some larger gyms outside. Because it's beautiful. Moreover, if you take good care of the packaged products for seven or eight years, there will be no problem. One hundred dollars is not enough for seven or eight years? And according to my many years of sports experience, I tell you: dumb ling is not as good as adding times by weight. Twenty pounds is used to practice explosive power. But ordinary people can't lift 20 Jin as two Jin, can they? In fact, it is enough for ordinary people to insist on practicing ten pounds. How can there be days in a year when you don't want to exercise or are not suitable for exercise? For example, if you have health problems, how many days are there in a year? It doesn't make much difference to use ten catties. You can still lose weight by weighing 10 Jin, but even if you are healthy, it is a little difficult to weigh 20 Jin, let alone if you are physically ill. If you don't do it, what is it for? Not waiting is a waste of money?
