Not all the people who go to the gym are old people, but some of them are sports whites. Don't worry, you can ask the coach if you don't understand the equipment. You can watch more fitness videos when you are free. If you have money, you can hire a personal trainer. You can watch what others do with equipment you can't use, and then practice with the lightest weight to ensure that the weight can be gradually increased, as long as you don't use it indiscriminately, throw it around or smash it. Pay attention to scientific fitness and don't get hurt.
