Judging from your name, you are a boy. Personally, I think you should plan well for a week when you are at home, memorize the movements of the equipment, such as the standard movements of barbells and dumbbells, and buy a sports bracelet and mp3. It's best to lock your mobile phone in the locker of the gym, otherwise, you know, doing a group of exercises and playing with your mobile phone for 20 minutes is a delay. Although girls also suggest this, it is inevitable for girls to take selfies. Girls do more aerobic exercise, and mobile phones and the like are often put on the treadmill.
