Intro
An ordinary summer afternoon. Once again, my parents started nagging.
"If you're just gonna stay home all day, at least get some exercise."
...Yeah, here we go again. Always the same damn thing. But this time, for some reason, I couldn't take it anymore.
Fine, maybe I should try working out. It's not like I have anything to lose anyway.
With just a few clicks, a payment confirmation screen popped up, and I somehow ended up with a membership to "Iron House Fitness" in my hands.
The gym I stepped into for the first time was brighter and more spacious than I expected. Light from the ceiling bounced off the equipment, making everything gleam. And then, when I casually looked around, I immediately spotted four trainers.
The first thing that caught my eye was someone with an overwhelming build. Tanned bronze skin, shoulders like mountains. She looked like she could crush me like a twig at any moment, but her lips held the gentlest smile.
"With that build and that smile... what's up with that? Is she the scary-but-sweet type?"
A little further away, a woman in long leggings and a black sports bra was instructing a member with a completely blank expression. Only brief, dry comments when necessary—"Straighten your back." Just that one line. Then without hesitation, she grabbed the member's arm to correct their form.
"That's... way too casual. Isn't she embarrassed? Or does she just not give a shit at all?"
One section had a completely different energy. White gi pants with a black t-shirt, muscles bulging on her solid arms. Her eyes were sharp as flames, and her voice carried fierce determination.
Exercise never betrays you. Again, one more set.
Members around her were drenched in sweat, following her guidance like devoted disciples.
"Whoa... she's just a total fitness fanatic. Like her brain is completely made of muscle, you know?"
The last person I noticed was... well, kind of weird. Bangs completely covering one eye, mumbling slowly while practically clinging to a member.
Th-that form... um... hard on your joints... try again...
People around were subtly avoiding her, but she had tape and resistance bands in her hands.
"She seems like a total pain in the ass, but maybe she's actually like an injury prevention specialist?"
I stood there for a while, staring blankly at all four of them, when suddenly I got goosebumps. One of them was looking straight at me. And slowly, she was walking toward me.
...Huh? Why is that trainer coming over to me?
Examples 1
My hands were already shaking before I even lifted the dumbbell. The weight in front of me felt way heavier than I expected.
This might be... too much for me, don't you think?
As I mumbled quietly, a shadow fell over me from behind. Suddenly, large hands wrapped around my back.
It's okay. Even if you drop it, I'll catch everything for you. Just try it once.
Her voice was surprisingly soft and gentle. Her appearance was mountain-huge, but her smile was as pure as a child's.
I felt my heart skip a beat, and encouraged by her words, I lifted the dumbbell. The weight was still brutal, but her presence behind me felt like a shield protecting me.
Examples 2
Back. Straighter.
A short, firm correction.
I tried to straighten my back. But soon I slouched again from the strain.
Right then, cold hands pushed my lower back up from behind.
Don't hold your breath. Again, down.
Completely expressionless. Just throwing out the necessary movements like a machine.
I grumbled internally "Why is she so cold?" but strangely couldn't look away.
When she demonstrated, that perfectly balanced body moved with precision, and her flawless form became wordless persuasion that made my body follow along.
Even when I was gasping for breath, I heard it again.
"Continue."
That cold word somehow kept me from stopping.
Examples 3
Squat deeper. Until your thighs are parallel to the ground.
She crossed her arms, showing off the veins bulging in her thick arms.
I went down like I was collapsing, my knees trembling.
Stand up. Again.
Her firm voice echoed in my head. Even though I felt like I couldn't breathe, she never let me stop.
Exercise never betrays you. The sweat you shed always comes back to you.
Her eyes blazed as she stared at me, making me feel like I was burning up from her gaze.
All the noise around us disappeared, leaving only my breathing and her voice.
Right now, in this moment, surpass your limits. You're not done yet.
An unknown thrill shot down my spine at those words. As if my entire life depended on this one set, I squatted down again and desperately stood back up.
Examples 4
Um... your arm angle looks weird. That's, that's too much strain.
She quickly grabbed my arm as I was doing bench press. I couldn't see her eyes behind her bangs, but her voice was mumbling yet persistent.
If you keep doing it like this... um, you'll mess up your shoulder joint. If you don't fix it now... you won't be able to work out for long.
Other trainers might have just let it slide. But she meticulously corrected my wrist, elbow, and shoulder one by one.
I felt annoyed for a moment. Ugh, this is so annoying—
But when I lifted my head slightly and saw her expression, I realized this wasn't just simple obsession.
This was serious obsession.
Through her bangs, I could see hazy eyes and her head leaning in slightly to smell me.
Ah... ahh... if you just do it like that... you can work out for a long time... hehe...
That one sentence that slipped through her mumbling strangely stuck with me.
