At that time, I didn't know that the thread at the back of my pants had fallen off. Fortunately, my fitness pants are black, and the inside is black, so it won't be too embarrassing.
I think my pants will collapse because I am riding a bike. I really gained weight in those days, and then my pants tightened. I rode my bike so hard that I didn't know my pants were open. Actually, I'm still a little proud after riding a bike. Alas, my pants seem a little loose (in fact, my pants are already open at the moment). Later, when others saw it, they reminded me. ......
Finally, I borrowed a pair of pants from the front desk lady of the gym and put them back on to continue my exercise. So it's very important to have a good relationship with the front desk lady in the gym!
Maybe you don't know how to use the treadmill or how to use the equipment when you go to the gym for the first time. If you don't want to ask the coach or gym members, you can quietly watch how the students next to you debug. My advice is to ask more questions.
Ask the coach, who will help you selflessly. The first time I went to the gym, I was really a mouse and didn't know anything. You'll get familiar with it after a long time in the back.
I suggest that you should keep good relations with the staff of the gym, male and female coaches, cleaning aunts, the front desk of the gym and other students, so that others will help you more or less if you encounter any embarrassing things in the future.
