We’ve all seen those clips. A mother lifts a literal sedan to save her child, or a sprinter like Usain Bolt makes world-class athletes look like they’re running through waist-deep molasses. It feels supernatural. You watch it and think, "That shouldn't be possible." But the reality is that the phrase you're impossibly fast and strong isn't just a compliment; it's a description of the human body hitting its absolute redline.
It happens. Not often. But it happens.

Most of us live our lives using maybe 30% to 60% of our actual physical potential. Our brains are essentially giant governors on an engine. If you actually used 100% of your muscle fiber recruitment on a random Tuesday morning to pick up a coffee cup, you’d likely snap your own tendons or shatter your humerus. The "impossibility" isn't a lack of strength; it's a safety protocol.
The Science of Hitting the Redline
When people talk about being impossibly fast and strong, they’re usually touching on "hysterical strength" or elite neuromuscular recruitment. Think about the 2006 case in Tucson where Tom Boyle Jr. lifted a Chevy Camaro to free a pinned cyclist. He didn't spend years powerlifting for that moment. His brain simply turned off the "don't hurt yourself" switch.
Research from institutions like the University of Washington suggests that adrenaline (epinephrine) acts as a chemical override. Usually, your Golgi tendon organs—tiny sensory receptors in your muscles—act as circuit breakers. They tell the brain, "Hey, stop pulling, or we’re going to tear off the bone." In a crisis, or under extreme pharmacological or neurological states, those breakers are bypassed.
You become a machine. For about sixty seconds.
But speed is a different beast entirely. It’s not just about raw power; it’s about the stretch-shortening cycle and the specific density of Type IIx fast-twitch muscle fibers. If you look at the DNA of elite 100m sprinters, you’ll almost always find the ACTN3 gene, specifically the RR variant. This gene codes for alpha-actinin-3, a protein found only in fast-twitch fibers. Without it, you might be fast, but you won't be "impossible."
Why You're Impossibly Fast and Strong in Moments of Crisis
Adrenaline is a hell of a drug. It’s the primary driver behind these bursts. When the amygdala senses a life-threatening stressor, it triggers the HPA axis (hypothalamic-pituitary-adrenal). This dump of chemicals increases your heart rate, dilates your pupils, and—most importantly—shunts blood away from your digestive system and directly into your skeletal muscles.
It’s a literal biological nitro boost.
Honestly, it’s kind of terrifying. People who have experienced this often report a "tunnel vision" effect. Time slows down. This is the tachypsychia phenomenon. Because your brain is processing information at a vastly accelerated rate, the external world seems to move in slow motion. This makes you feel like you're impossibly fast and strong because you are reacting to stimuli before they’ve even fully registered in your conscious mind.
The Cost of Breaking Physics
There is no free lunch in biology. Never.
If you push your body to these "impossible" limits, you pay for it. Tom Boyle, the guy who lifted the Camaro, reportedly lost several teeth from clenching his jaw so hard during the lift. People who experience hysterical strength often collapse immediately afterward because their ATP (adenosine triphosphate) stores are utterly decimated. Your muscles are essentially running on fumes and sheer willpower.
Modern Athletics and the "Impossible" Standard
In the world of professional sports, we are seeing the "impossible" become the baseline. Look at Erling Haaland on a football pitch. He’s 6'4", weighs nearly 200 lbs, and yet he moves with the grace and acceleration of a point guard. This isn't just luck. It's the result of plyometric training that optimizes the myotatic reflex.
By training the nervous system to react faster to the stretching of muscle fibers, athletes can produce force almost instantly.

The gap between a normal person and an elite athlete isn't just muscle size. It's the speed of the signal. The "Rate of Force Development" (RFD) is what determines if you're fast or if you're impossibly fast and strong. Most people take about 300 milliseconds to reach peak force. An elite sprinter does it in less than 100 milliseconds.
The Limits of Human Potential
So, is there a ceiling? Probably.
Dr. Peter Weyand, a leading expert in locomotion at Southern Methodist University, has studied the mechanics of sprinting for decades. He suggests that the limiting factor for human speed isn't how fast we can move our legs—it's how much force we can hit the ground with in a tiny window of time.
The "impossible" threshold for a human 100m sprint is theorized to be around 9.27 seconds. To get there, a human would need to be even stronger without adding any significant mass. It's a catch-22. Muscle adds weight, and weight slows you down.
How to Tap Into Your Own Potential
You probably won't be lifting cars tomorrow. And honestly? You shouldn't want to. But you can improve your own "fast and strong" metrics by focusing on the nervous system rather than just the muscles.
- Focus on Post-Activation Potentiation (PAP): This is a fancy way of saying you should do a heavy lift before an explosive movement. It "wakes up" the central nervous system.
- Prioritize Sleep: Your nervous system recovers much slower than your muscles. If you’re fried, you’ll never be fast.
- Plyometrics: Box jumps and depth jumps train your tendons to act like springs. Springs are faster than motors.
- Mindset: The "governor" in your brain is real. Overcoming it requires incremental exposure to high-intensity stress.
Real-World Examples of the Impossible
We have to look at the 1968 Olympics in Mexico City. Bob Beamon’s long jump. He didn't just break the world record; he shattered it by nearly two feet. It was a "perfect storm" of altitude, wind, and a neurological peak that he never came close to hitting again. He literally collapsed when he realized what he had done. His body had reached a level of output that his mind couldn't even process.
Then there’s the sheer power of someone like Mariusz Pudzianowski in his prime. The five-time World's Strongest Man moved weights that seemed to defy the structural integrity of human bone.
These aren't just stories. They are data points on the far end of the Gaussian distribution.
Actionable Insights for Increasing Power
If you want to feel what it's like when you're impossibly fast and strong, you have to stop training like a bodybuilder. Bodybuilding is about aesthetics and volume. Speed and strength are about intensity and neurological efficiency.
Start by implementing max effort days. Don't do 10 reps. Do one rep at 95% of your capacity. This teaches your brain to recruit every single available fiber. Use "overspeed" training, like sprinting downhill or using bungee cords to pull you faster than you can naturally run. This forces your brain to adapt to a higher turnover rate.
It's uncomfortable. It's taxing. But it's how you move the needle from "average" to "impossible."
The human body is a masterpiece of restraint. We are built to survive, not to perform like superheroes every day. But the potential is there, buried under layers of biological safety nets. When those nets drop—whether through years of elite training or a split-second survival instinct—the result is nothing short of miraculous.
To actually improve your functional output, you must focus on the quality of movement and the speed of contraction. Strength without speed is just mass; speed without strength is just movement. The intersection of both is where the magic happens.
Focus on explosive, compound movements like the clean and press or the kettlebell swing. These movements require the entire body to work as a single, cohesive unit. They mirror the way we moved in the wild, and they are the fastest way to bridge the gap between your current self and your peak potential.
