A power belly is the large, protruding midsection common among elite strongman competitors and heavyweight powerlifters. Unlike typical belly fat, a power belly combines thick abdominal muscle with a layer of body fat, creating a solid, round gut that sticks out further than the chest. In strength sports circles, it’s sometimes called a “one pack” or a “Buddha belly,” and it’s considered a badge of honor rather than something to hide.
Why Strong Athletes Have Big Bellies
The power belly isn’t just excess weight. Years of heavy squatting, deadlifting, and overhead pressing thicken the entire trunk, including the abdominal muscles themselves. Your core is muscle, and like your arms or legs, it grows in response to training. When you’re regularly bracing against hundreds of pounds of weight on your back, the muscles of your midsection get substantially thicker over time.
On top of that muscular base sits a layer of body fat from the calorie surplus required to fuel extreme strength. Elite strongman competitors routinely eat 7,000 to 10,000 calories per day (or more) to maintain bodyweights above 300 pounds. Brian Shaw, a four-time World’s Strongest Man winner, has publicly documented daily intakes reaching 15,000 calories during peak training. That kind of eating builds both muscle and fat, and the midsection is where much of it settles.
The result is a belly that looks soft on the outside but feels remarkably hard underneath. It’s dense, packed with both muscle and internal pressure, not the squishy midsection you’d get from years on the couch.
How a Bigger Belly Helps You Lift More
A power belly actually serves a mechanical purpose during heavy lifts. When you take a deep breath and brace your core before a squat or deadlift, you’re building what’s called intra-abdominal pressure: essentially turning your torso into a rigid cylinder that protects your spine. A thicker midsection creates more surface area to pressurize, which translates to a more stable trunk under extreme loads.
This effect becomes even more pronounced with a weightlifting belt. When you expand your belly into a belt, you can increase that internal pressure by 25 to 40 percent compared to bracing without one. A larger abdomen means more contact with the belt and a greater pressure boost during the initial surge of a lift. That extra stability reduces compressive forces on the spine, which is critical when you’re pulling 800 pounds off the floor.
For competitive strength athletes, this isn’t a minor advantage. It’s one reason why the strongest humans in history have almost universally carried significant midsections. Žydrūnas Savickas, Eddie Hall, Mark Henry, Brian Shaw, Andy Bolton: all legends of strength, all sporting unmistakable power bellies at the peak of their careers.
Power Belly vs. Regular Belly Fat
The key difference is what’s underneath. A power belly sits on top of a heavily developed core musculature built through years of progressive heavy lifting. Someone with a sedentary lifestyle carrying the same waist measurement would have a fraction of the abdominal muscle mass and far less ability to generate trunk stability.
That said, the distinction matters more for performance than for health. From a metabolic standpoint, the fat component of a power belly carries real risks. High levels of visceral fat (the deep fat surrounding your organs) are associated with a 70 percent increased risk of metabolic syndrome, which includes elevated blood pressure, high blood sugar, and abnormal cholesterol levels. This holds true regardless of how strong you are. Many retired heavyweight strength athletes have spoken openly about improving their health by losing significant weight after competition.
Do You Need One?
Almost certainly not. The power belly is a side effect of training and eating at the absolute extremes of human performance. If you’re not competing as a super heavyweight lifter, there’s no reason to pursue one deliberately. You can get significantly stronger while staying at a moderate body fat level.
Heavy compound lifts will naturally thicken your core over time, and you may notice your midsection growing even as your body fat stays reasonable. That’s normal and healthy. It’s the muscular component doing its job. But the full-blown power belly, where your stomach enters a room before you do, is the product of eating thousands of surplus calories daily for years while training at world-class intensity. It’s a tool for a very specific job, not a fitness goal for most people.
For the athletes who carry one, though, it represents something real: the physical evidence of pushing the human body to its limits. As one strength coach put it, some of the strongest men to ever walk this planet had a glorious gut.
