Look at your problem. I guess you ran to the free equipment section as soon as you got to the gym. If you are a novice in fitness, practice the basic equipment for about a month first, so that your body can adapt to the equipment first. Wait until you have a certain foundation before making barbell equipment. According to your situation, you are also weak in muscle endurance. You should improve your muscle endurance first. You have no endurance. No matter how strong a person is, pushing one or two groups will have no strength and will not play much role in muscle development. I suggest you do push-ups first, and when a group can do about 50, stick to four groups, and slowly practice barbells will get twice the result with half the effort.
