Humans are the planet’s top predators. Our species is intelligent and creative enough to figure out how to kill anything. Sadly, we design weapons that can change the world as we know it. However, if you take away all our tools, we’re not that tough. In fact, many animals can pose significant threats to us. That’s why we’re exploring whether an unarmed human can beat a lion in a one-on-one fight.
We’ll break down the various elements of this fight and show you what to expect if you find yourself going head-to-head with the King of the Jungle.

defense | – Human intelligence allows for the development of shelters, armor and traps to prevent damage – Unarmed humans have little defensive advantage other than stamina and intelligence – Good vision and hearing help humans spot animals – Relatively fragile body with various weaknesses | – Protected by prides of lions in many cases – The mane protects the neck from bites – Primal strength makes it hard for any animal to take down a lion – Speed helps the lion escape from enemies |
offensive ability | – May punch, kick, grapple or otherwise attack prey – Can bite with relatively weak bite force and small canines – Can use intelligence to lure animals into unfavorable situations | – The claws are 1.5 to 2 inches long and can chop meat – Bite force between 650 and 1,000 PSI can easily break bones – 2 to 4 inch canines penetrate deep into the flesh – Can slap prey with its claws and cause significant damage |
predatory behavior | – Cursorial Predator and Ambush Predator, but only with weapons | – Ambush a predator, usually when hunting alone or with others – Acts as a sketchy predator in some cases, consuming prey before killing them |
What is the key factor in a fight between an unarmed man and a lion?
As with all fights that take place in the wild, a fight between an unarmed human and a lion boils down to five main factors. They are size, predatory behavior, speed, defense and offense. Each of these elements affects combat.
So figuring out whether a man or a lion is alive in this race means we need to compare information and determine which animal has an advantage in a particular situation. Afterwards, we’ll discuss how the battle will play out based on these factors. let’s start!
Unarmed Humans Versus Lions: Size

Lions are bigger than people. Lions weigh between 260 and 550 pounds on average and can reach a height of 3.9 feet and a length of 8.2 feet. Meanwhile, the average unarmed person weighs about 130 to 199 pounds and stands between 5 feet 3 inches and 5 feet 9 inches tall. Of course, there are larger humans around too.
Still, lions have a size advantage in this fight.
Unarmed Men and Lions: Velocity

Lions are much faster than humans. Lions can run comfortably at 35 miles per hour. However, the moment they are about to reach their prey, they can reach speeds of 40 to 50 miles per hour.
The average human running speed is between 6.5 and 8 mph. The fastest man reached 27.5 mph in a full sprint. This speed is beyond the reach of most people.
Lions have a significant speed advantage.
Unarmed Man vs. Lion: Defense
Lions are known to live in a pride, with other members of their pack helping them protect themselves from harm. On a physical level, their large size and strength make them very difficult to knock down and kill. Also, they have the speed to help escape from adverse situations. They also have manes that protect their fragile necks from bites.
Without weapons or armor, humans are very fragile creatures. Unarmed humans will have to rely on their senses to identify and avoid danger, while using their intellect to create plans to stay safe. This doesn’t help much in the fight against wild animals.
The Lions have the advantage in physical defense.
Unarmed Men and Lions: Offensive Capabilities
Lions are aggressive and strong. They prefer to strangle their prey with a powerful bite. Their 650 to 1,000 PSI bite force is more than enough for the animals they hunt. Helpfully, they have 3 to 4 inch long fangs that can inflict deep stab wounds and help them break vertebrae and skulls. Lions also have the ability to hit animals with their paws and cause significant damage. Finally, they can tear apart the flesh of their prey with their claws. They are ready for battle.
Unarmed humans are hardly prepared for hand-to-hand combat. We can punch, choke, wrestle, or bite other animals. However, our bite force is weak and our teeth are relatively small. It is impossible for humans to punch and kick lions.
The Lions have a clear advantage in offensive ability.
Unarmed Humans Versus Lions: Predatory Behavior
Lions can use two hunting methods. They either ambush their prey and kill it instantly, or use multiple attackers to exhaust it and kill it. The way they attack depends on what animal they are hunting and whether the lion is alone or with other people.
When humans use tools and weapons, they use a variety of different hunting strategies. However, their best bet is to use an ambush attack when unarmed.
Lions have an edge when it comes to predation behavior.
Who would win in a fight between an unarmed human and a lion?

No, an unarmed man can’t beat a lion. Even if a human encounters a sleeping lion, the chances of killing it are ridiculously small. Humans don’t kick or punch a lion down. Nor do they strangle a lion. So, how do they win this battle?
Of course, humans can run away and try to hide from this creature. However, lions are good hunters, and if they’re hell-bent on killing a human being, they won’t have any trouble.
A lion can use any attack it wants to kill an unarmed human. The most likely form of attack is to jump on top of a person and bite their head or neck, causing rapid blood loss and massive trauma.
From time to time lions will kill armed humans. For an animal of this size, they are deadly, hard to kill, fast, and deceptively sneaky. If it is difficult for a man with weapons to kill a lion, then an unarmed man has no chance.
It goes without saying, but don’t try to attack wild animals. Leave them alone.table top

I am broadly interested in how human activities influence the ability of wildlife to persist in the modified environments that we create.
Specifically, my research investigates how the configuration and composition of landscapes influence the movement and population dynamics of forest birds. Both natural and human-derived fragmenting of habitat can influence where birds settle, how they access the resources they need to survive and reproduce, and these factors in turn affect population demographics. Most recently, I have been studying the ability of individuals to move through and utilize forested areas which have been modified through timber harvest as they seek out resources for the breeding and postfledging phases. As well I am working in collaboration with Parks Canada scientists to examine in the influence of high density moose populations on forest bird communities in Gros Morne National Park. Many of my projects are conducted in collaboration or consultation with representatives of industry and government agencies, seeking to improve the management and sustainability of natural resource extraction.
