When people watch elite female gymnasts, one thing that often stands out is their legs, especially their thighs. Tight leotards and powerful moves make this area easy to notice. But for those not used to athletic bodies, these strong thighs are sometimes mistaken for “fat.”
So, are they really fat? Or are they just strong, muscular legs built for performance?
The Misunderstanding: Why Muscle Gets Mistaken for Fat
A lot of the confusion comes from outdated ideas of what a “feminine” body should look like. Society tends to equate being slim with being beautiful. So when someone sees big, muscular thighs on a gymnast, they might misjudge them.
Why Gymnast Thighs Are Often Called “Fat”:
- We expect slim legs: Many people grow up thinking that thin legs are the standard of beauty. Muscular legs don’t always fit that image.
- Short height makes muscles look fuller: Most gymnasts are under 5′3″, which means their muscle mass is packed into a smaller frame—making it seem like their thighs are “wider.”
- It’s just unfamiliar: If you’re used to seeing untrained legs, muscular ones might look “big” even though they’re lean, strong, and efficient.
But here’s the truth: elite gymnasts usually have low body fat. Their thighs don’t come from overeating or lack of health—they come from hard, focused training.
Why Gymnasts Need Strong Thighs
Everything in women’s artistic gymnastics relies on leg power. The thighs are involved in nearly every skill and event:
- Vault: Running and launching off the springboard needs serious quad and glute strength.
- Floor: Tumbling takes sprinting speed and the ability to rebound off the ground.
- Beam: Leaps, jumps, and tight landings depend on leg control and balance.
- Bars: Even here, leg drive is key in dismounts and transitions.
This kind of training shapes the thighs over time, building muscle in the quads, hamstrings, glutes, and hip flexors. Strong thighs aren’t just helpful—they’re necessary.
How Gymnasts’ Thighs Compare to the Average Woman
Here’s a simple side-by-side comparison based on general health data:
| Feature | Average American Woman | Elite Female Gymnast |
|---|---|---|
| Height | ≈ 163 cm (5′4″) | 150–153 cm (4′11″–5′0″) – common elite range |
| Weight | ≈ 77 kg (170–171 lb) | 45–50 kg (99–110 lb); Simone Biles ~47 kg |
| Body Fat % | 25–31% healthy range; often 32–42% with age | 13–16% (elite level); up to ~23% (collegiate) |
| Thighs | Average muscle tone, higher fat proportion | High muscle definition, low fat—lean and dense |
Muscle, Not Fat: The Science Behind Gymnast Thighs
Sports science labs often measure body composition using tools like DEXA scans or skinfold calipers.
Across multiple studies, senior international female gymnasts consistently fall between 10% and 16% body fat—far below the 20–30% typically found in non-athletic women of the same age. This tells us that the bulk you see on a gymnast’s legs is made up of lean, powerful muscle, not excess fat.
Muscle is about 18% denser than fat, meaning it takes up less space pound-for-pound. But because muscles develop in specific areas depending on training, gymnasts can have wide, muscular thighs while still having a narrow waist and low overall body fat.
When you see a gymnast with strong-looking thighs, it helps to understand what’s there:
- Muscle is heavier, full of water, and made for power and protecting joints.
- Fat is lighter, stores energy, and mainly helps with insulation.
Gymnasts have more muscle, not fat. That strong muscle helps them balance on a narrow beam and flip through the air with power. So when their thighs look bigger, it’s not a bad thing—it’s a sign of strength.

How Gymnasts’ Legs Change During Puberty
As gymnasts grow up, their bodies naturally change, especially during puberty. One of the biggest changes is how fat is stored in the body. For girls, the hormone estrogen increases during puberty, and this causes more fat to be stored around the hips and thighs, even in athletes.
So if a gymnast’s legs look a little fuller, it doesn’t mean they’re gaining unhealthy weight. Here’s what’s really happening:
- Some healthy fat is added to the hips and thighs as part of normal development.
- Their strong muscles are still there and keep growing with training.
- The result is legs that look a bit curvier or bigger—but they’re strong and healthy.
It’s also normal for gymnasts to feel unsure about these changes. Their bodies may not look like they used to, and that can be confusing. But this stage is completely normal and happens to all girls, whether they do gymnastics or not.

Why Strong Is the New Standard in Gymnastics
In a world full of filters and unrealistic beauty standards, it’s easy to forget what real strength looks like. Social media often promotes slimness as the ideal, which can make muscular thighs seem “different.” But in gymnastics, strong legs aren’t unusual—they’re essential.
Gymnasts like Simone Biles, Sunisa Lee, and Jordan Chiles are changing how people think about athletic bodies. Their powerful legs aren’t a flaw—they’re what make them fly higher, twist faster, and land with precision. Their bodies aren’t shaped for appearance—they’re built for performance.
Simone Biles
Widely considered the greatest gymnast of all time, Simone’s strength is legendary. Her muscular legs give her the power to perform skills no other woman has ever done. Some people have criticized her build, calling her “stocky,” but that strength is exactly what sets her apart—and she’s proud of it.
Aly Raisman
A two-time Olympian and team captain, Aly has been open about body image struggles in gymnastics. She’s spoken out about how strong thighs represent years of dedication—and how athletes should never feel ashamed of the way strength looks.
These women aren’t trying to meet someone else’s beauty standard. They train to be strong, focused, and fearless—and their bodies reflect that.
Final Words: A Better Way to See It
So, do female gymnasts have bigger thighs than the average woman?
Yes—if you mean stronger, more powerful, and built for performance. Not necessarily heavier or fatter.
Instead of asking: “Why are their thighs so big?”
Let’s ask:
“How did they get that strong?”
“What can we learn from a body built for power?”
Gymnasts train harder than most of us can imagine. Their thighs aren’t something to criticize—they’re something to admire. It’s time we celebrate strength as part of what makes someone beautiful.
