For beginners, it's a little confusing when they first enter the gym. They don't know where to start. Don't be too eager to exercise. You can warm up from the treadmill first. Don't run directly. You should do stretching before running, or you will strain your muscles. At first, I suggested jogging to give the body an adaptation period, otherwise it would be easy to have backache the next day.
It is normal for the body to feel sore. This is because you lack exercise. You can continue to exercise at this time. Don't stop exercising because your muscles are sore. Then your muscles will feel sore the next time you exercise.
After a period of time, you can gradually understand the equipment in the gym. For equipment, girls can practice their backs first, because most people's backs are not very straight. Practicing their backs can improve your temperament and make your figure straighter. If it's a boy, you can start with dumbbells. In addition, you should wear loose and comfortable clothes when going to the gym, and you can wear tight pants when practicing yoga, but you must be comfortable.
