12-3-30, 75 Hard & Beyond: What Gen Z Really Thinks About FitTok

FitTok Takeover: Are Viral Fitness Challenges Actually Worth It?

Okay, so picture this: you’re deep in your 2 a.m. scroll hole on TikTok. One swipe shows a girl absolutely glowing after day 12 of the 75 Hard Challenge. The next? Someone swears their life changed doing the 12-3-30 treadmill workout for 30 days. Suddenly, you're wondering if the key to unlocking your glow-up is just one viral challenge away.

Welcome to FitTok, where Gen Z turns fitness into content, and your “For You Page” becomes a gym you never asked to join.

But here’s the real question: are these trendy challenges actually good for you? Or are they just fitness fads dressed in crop tops and over-filtered results? We dug into the sweat, science, and stories behind the internet’s most viral workout trends — and what Gen Z really thinks about them.

🎥 What Even Is FitTok?

FitTok is that chaotic, sweaty corner of TikTok where fitness trends go from niche to viral fast. We're talking millions of views on videos that promise insane transformations in 2-4 weeks. No equipment? No problem. No background in fitness? Just follow along.

It’s accessible, free, and lowkey addicting. But it’s also a space where the line between motivation and pressure gets blurry real quick.

💨 The Challenges That Took Over Our Screens

1. 12-3-30

The pitch: Walk on a treadmill at a 12% incline, at 3 mph, for 30 minutes.

The vibe: Low-impact, deceptively simple, and a certified glute killer.

What Gen Z thinks:

“It’s great for lazy girl cardio. I just throw on a show and vibe.”
— Riley, 22, Boston

The catch: Not all treadmills even go to 12% incline, and it can wreck your calves if you go in cold.

2. 75 Hard

The pitch: 75 days of strict routine: two 45-minute workouts daily, clean eating, no alcohol, read 10 pages of a book, drink a gallon of water. No cheats. No excuses.

The vibe: Grit. Hustle. Hustle. Grit. Did we mention hustle?

What Gen Z thinks:

“I made it to Day 9. It’s not a challenge — it’s a bootcamp disguised as self-help.”
— Jayden, 24, LA

The catch: Mentally intense. Super restrictive. Borderline toxic if you don’t allow space for real life.

3. Hot Girl Walks

The pitch: Go on a walk. That’s it. Bonus points for manifesting your dream life while doing it.

The vibe: Movement meets mental health.

What Gen Z thinks:

“My anxiety lowers, my confidence goes up, and I get steps in? She’s that girl.”
— Tessa, 20, Austin

The catch: If you’re chasing fitness results, this won’t replace strength training. But for sanity? 10/10.

4. Grow Your Glutes in 30 Days

The pitch: Squat, hip thrust, repeat — with daily at-home glute-focused workouts.

The vibe: Body goals. Peach emoji in real life.

What Gen Z thinks:

“My butt’s kinda bigger. But honestly, it’s the confidence that grew more.”
— Isaiah, 21, Toronto

The catch: Muscle growth takes time, consistency, and rest — something these quick challenges skip over.

🧠 The Psychology of the "Challenge Culture"

There’s something addictive about a start and end date. It’s why these trends go viral. The promise of a visible glow-up in X number of days is tempting — and when it’s being served by hot people with great lighting, the pressure hits.

But here’s the thing: a challenge is only as sustainable as your life allows. And too often, Gen Z is left feeling like they “failed” when they don’t make it to Day 30 or 75. That’s not healthy — and it’s definitely not the point of movement.

🩺 Expert Check-In: What Trainers Say

Certified personal trainer Aaliyah Kim (@trainwithlee) says FitTok is a double-edged sword.

“It’s amazing that so many young people are moving more because of TikTok,” she says. “But most of these trends lack proper rest days, progressive overload, and realistic expectations.”

She adds, “Fitness isn’t one-size-fits-all. A workout challenge should never make you feel like you’re being punished.”

👟 Real Talk: Should You Try One?

Here’s the honest tea:

✅ Do it if…

• You need a short-term motivation boost.
• You know your limits.
• You’re cool with adjusting the rules to fit your life.

🚫 Maybe skip if…

• You’re recovering from disordered eating or exercise habits.
• You feel guilty for missing a day.
• You're chasing results over sustainability.

The best fitness plan? The one you’ll actually stick to without hating your life. Whether that’s a viral challenge, dance cardio, or lifting in your garage with your dog watching — do you.

Fitness should feel like freedom, not punishment. Keep it real, keep it fun — and always keep it Gen Z — with Woke Waves Magazine.
