You’ve probably seen the memes. A tiny, delicate-looking horse girl like Rice Shower or Haru Urara suddenly sporting a physique that would make a professional bodybuilder weep. It’s the power lifter Uma Musume phenomenon. While Cygames’ Uma Musume Pretty Derby is technically a racing sim, the community has turned "Power" into more than just a stat. It’s an aesthetic. It's a subculture.
Honestly, it’s hilarious. But there is a real mechanical reason why players obsess over these maxed-out Power builds.
In the game, Power determines how well your girl can push through a crowd. If she’s boxed in at the final corner, she needs raw strength to shove past rivals. Without it, she’s stuck. She loses. This mechanical necessity birthed a massive wave of fan art and "power lifter" edits that reimagine these idols as absolute units. We aren't just talking about a little muscle tone here. We’re talking about veins popping, traps for days, and quads that could crush a watermelon.
The Mechanics of Muscle
Let’s get technical for a second. In the Uma Musume engine, Power ($\text{Power}$) works alongside Stamina ($\text{Stamina}$) and Speed ($\text{Speed}$). If you have 1200 Speed but only 400 Power, your horse girl is basically a glass cannon. She’ll fly on an open track, but the moment she hits traffic? It's over. She lacks the "burst" to accelerate out of a cluster.
This is why the power lifter Uma Musume archetype became a thing. Serious players started prioritizing the Power stat in specific scenarios, particularly for "Between" (Sashi) or "Chaser" (Oikomi) runners. These girls stay at the back and then explode forward at the end. To do that, they need to be strong. Really strong.
Most people get the "Power" stat wrong by thinking it's about top speed. It’s not. It's about acceleration and positioning. It's the "Oomph" behind the sprint. When you see a Gold Ship or an Oguri Cap suddenly lunge forward in the final 200 meters, that’s her Power stat doing the heavy lifting.
Why the Fandom Went Overboard
The contrast is the point. You have characters designed with the "moe" aesthetic—big eyes, soft features, cute outfits—and then you overlay the physique of an Olympic weightlifter. It’s a jarring, funny, and weirdly inspiring juxtaposition.

Fans started using AI image generators and high-level Photoshop skills to create "Buff Uma Musume" edits. It’s become a staple of the Twitter (X) and Pixiv communities. Some artists, like those who focus on "Muscle Uma," have gained thousands of followers just by drawing Mihono Bourbon or Grass Wonder with eighteen-inch biceps.
It’s a bit of a subversion of the "idol" trope. Instead of being fragile, these girls are depicted as the elite athletes they technically are. If you’re running 2000 meters at breakneck speeds, you aren't going to have skinny little legs. You're going to be built.
Training for the Power Build
If you’re actually trying to build a power lifter Uma Musume in the game, the strategy is specific. You can't just spam the Power training button. You'll run out of Stamina or fail your speed checks.
- Inheritance is King: Use parents with 9-star Power factors. This gives you a massive baseline without wasting early-turn energy.
- Support Card Synergy: You need cards that offer "Power Bonus." Cards like SSR Yaono Muteki or SSR El Condor Pasa are legendary for this. They don't just give you points; they give you the skills that make that power useful, like "Killer Tune" or "Aggressive Footwork."
- The Training Method: In scenarios like U.A.F. Ready!! or L'Arc, you have to balance your "trials." Focus on the red (Power) training when the multipliers are high, but never ignore the blue (Stamina) or you’ll "outrun" your own energy reserves and collapse before the finish line.
It’s a delicate dance. You want that 1200+ Power rating, but if your Speed is sitting at 600, you’re just a very strong person moving very slowly. You'll look great, but you'll finish last.
Misconceptions About the "Power" Stat
A lot of newbies think Power helps with hills. It does, but only partially. Guts ($\text{Guts}$) actually plays a massive role in hill climbing and maintaining speed under pressure. If you build a power lifter Uma Musume and she still fails on the uphill sections of Nakayama or Hanshin, it’s probably because your Guts stat is trash.
Also, Power doesn't help with "Start Dash." That’s mostly Intelligence ($\text{Wisdom}$) and specific skills like "Concentration." Power is strictly for the mid-to-late game struggle for lane positioning.

The Cultural Impact of the "Buff" Meme
Why does this keep trending? It’s basically the "Swole Doge" meme but for anime fans. It represents the grind. Training a horse girl in Uma Musume is notoriously difficult. It’s a rogue-like experience where one bad RNG roll can ruin a thirty-minute run. When players finally hit that "S+" or "UE" rank with maxed stats, it feels like they’ve personally spent hours in the gym.
Representing that effort through a muscular character design just makes sense. It’s a visual shorthand for "I spent three days straight trying to get this specific build, and now she's a god."
Real-World Racing vs. The Game
In actual horse racing, power is about the "hindquarters." If you look at a real champion sprinter, their back end is massive. That’s where the drive comes from. The game translates this into the Power stat. While the power lifter Uma Musume fan art might be an exaggeration, the spirit is grounded in biology. Fast things need big muscles to produce force.
Force equals mass times acceleration ($F = ma$). To get that acceleration ($a$) high for a 500kg animal (or a 50kg girl), you need a lot of force ($F$). Simple physics.
How to Get Started with Your Own Power Build
If you want to dive into this, stop focusing on the "Standard" builds you see on Wikis. They're often optimized for generic wins. If you want a specialized Power monster for specific tracks like the Arima Kinen or the Japan Cup, you have to be willing to sacrifice a bit of Wisdom.
- Look for "Power" training bonuses on your support cards.
- Prioritize "Overflow" training during the summer camp phase.
- Don't be afraid of the "Overwork" penalty if you're close to a milestone.
Honestly, there’s something deeply satisfying about seeing a "Power" stat hit the gold cap. It changes the way the sprite moves on the screen—or at least, it feels like it does. You see her shove an opponent out of the way, and you think, "Yeah, that's my power lifter."

Actionable Steps for Your Next Training Run
Stop following the "all-around" guides. They make boring characters.
First, pick a girl with a natural Power growth bonus. Look for that $+10%$ or $+20%$ Power icon on her profile. Oguri Cap and Vodka are great starting points. Second, stack your deck with at least three Power support cards. Third, ignore the "Speed" meta for just one run. Try to max out Power first.
You’ll notice the difference in the replays. She won't just run; she’ll dominate the lane. She’ll become the power lifter Uma Musume you’ve seen in the memes. Even if you don't win every race, watching her steamroll through a pack of fifteen other runners is its own reward.
Go to the training menu. Pick your favorite girl. Smash that red button until she’s a legend.
The goal isn't just to win. The goal is to be undeniable. In the world of Uma Musume, being the strongest is often just as good as being the fastest. Usually better, if you ask the fans.
Check your inheritance factors now. If you don't have at least six stars in Power from your friends' list, go find some new followers. You can't build a powerhouse on a weak foundation. Get to work.
