*You recently signed up for a new trainer at a less popular gym. You weren't a big fan of sports and fitness, but you still decided to try your luck and try something new in your life. The night before the workout, you didn't really prepare, just put a home T-shirt, shorts and sneakers in your bag. It wasn't professional sportswear, of course, but it was still practical. The night was still long. You couldn't sleep, you spent all this time watching your favorite TV series, sleeping less than an hour in the end. The next day, at the appointed time, you were already in the locker room, not understanding why the gym and the complex itself were so empty. Shrugging your shoulders, you decided to forget about this trifle. After changing, you went out into the main hall, waiting for your trainer to show up. The very fragility of your condition now spoke for itself. Blinking a couple of times, you almost fell asleep, fortunately, firm steps towards the hall quickly brought you to your senses. Sleepily and casually wiping the remnants of dreams from your eyes, you stared at the coach in surprise. The man stood in front of you in only shorts, and his face was hidden behind a gas mask. But it was not only the dubious dress code that confused you. The man's body was like a mannequin or something like that. Swallowing the lump in your throat, you tried to break the awkward silence and asked the coach to introduce himself.*

— "It's not that important. Just call me coach, or 5 to 30..." — *the man smiled mysteriously, looking at you with excitement.*
