Human muscles are already stronger than they need to be. The brain limits how strong any muscle in the body can pull, otherwise, we could break our own arms by clenching our fists. It's difficult to say which muscle is the strongest in the human body because few muscles work alone. Some people say the jaw muscle is the strongest by weight, but certain thigh muscles can exert more force. Physiologists debate whether the strongest muscle is the masseter (used for chewing), the gluteus maximus (buttocks), or the rectus femoris (part of the quadriceps in the thigh).

What You'll Learn
The strongest muscle in the human body
It's difficult to say which muscle is the strongest in the human body because few muscles work alone. However, there are several contenders for the title.
The masseter, or jaw muscle, is a contender for the strongest muscle in the human body. This thick cheek muscle near the back of the jaw opens and closes the mouth when you chew. Some physiologists believe the masseter is the strongest muscle in the body.
The gluteus maximus, or buttocks, is another contender for the strongest muscle in the body. This is the largest muscle in the human body and has the job of keeping the trunk of the body in an erect posture.
The rectus femoris, or quadriceps in the thigh, is also a candidate for the strongest muscle in the body. However, it is difficult to compare this muscle to others because other quadriceps muscles contract along with it.
The soleus, or calf muscle, is another strong muscle. Without this muscle, we wouldn't be able to stand, walk, run or dance.
Finally, the tongue is also a very strong and flexible muscle. Its combination of elasticity and forcefulness gives us the ability to speak, eat and kiss.

Muscles and adrenaline
It is difficult to say which muscle is the strongest in the human body as few muscles work alone. Some people say the jaw muscle is the strongest by weight, while others claim it is the gluteus maximus (buttocks) or the rectus femoris (part of the quadriceps in the thigh).
The human body is already stronger than it needs to be. Adrenaline can make people do things that others would consider "metal", such as deadlifting a car. Adrenaline gives your muscles a boost of energy by binding to receptors on liver cells to break down larger sugar molecules into a smaller, more readily usable sugar called glucose. It also increases your heart rate, makes your lungs breathe more efficiently, and sends blood to your muscles. Adrenaline also shortens the duration of the slow calf muscle twitch, but has no effect on the fast twitch of adductor pollicis.

How much strength is too much strength?
It's difficult to say how strong human muscles are, as few muscles work alone. Some people say the jaw muscle is the strongest by weight, but certain thigh muscles can exert more force. Physiologists believe the strongest muscle in the body is the masseter (used for chewing), while others claim it's the gluteus maximus (buttocks), or the rectus femoris (part of the quadriceps in the thigh).
So, how much strength is too much strength? Well, your muscles are already stronger than they need to be. Your brain limits how strong any muscle in your body can pull, otherwise, you could break your own arm by clenching your fist. However, an enraged person with a lot of adrenaline in their system can do things that might be considered 'metal', like deadlifting a car.
If you had 10x the strength, your body wouldn't be able to handle it. You'd break bones, dislocate joints and tear muscles no matter how much strength you had. You wouldn't look like a normal human being anymore. You might be strong enough to bench press a big motorcycle, but since it outweighs you, you wouldn't be able to use it as a weapon.

The strongest muscle in the human body by weight
It is difficult to say which is the strongest muscle in the human body by weight, as few muscles work alone. Some physiologists believe it is the masseter, the primary muscle used for chewing, while others claim it is the gluteus maximus (buttocks), or the rectus femoris (part of the quadriceps in the thigh).
The gluteus maximus is the largest muscle in the human body. It is large and powerful because it has the job of keeping the trunk of the body in an erect posture. It is the chief antigravity muscle that aids in walking up stairs.
The heart is the hardest-working muscle, pumping out 2 ounces (71 grams) of blood at every heartbeat. Daily, the heart pumps at least 2,500 gallons (9,450 litres) of blood. The heart has the ability to beat over 3 billion times in a person's life.
According to Gray's Anatomy, the soleus, or the calf muscle, is the muscle that can exert the most force. Without this muscle, we wouldn't be able to stand, walk, run or dance.
Your muscles are already stronger than they need to be. Your brain is limiting how strong any muscle in your body can pull. If it didn't, you could break your own arm by clutching your fist.

The strongest muscle in the human body by force
It's difficult to say what the strongest muscle in the human body is because few muscles work alone. However, there are several contenders for the title.
The masseter, or the jaw muscle, is the strongest muscle based on its weight. It is the primary chewing muscle and is able to exert force quickly. In 1986, Richard Hofmann of Lake City, Florida, achieved a bite strength of 975 pounds (442 kilograms) for two seconds, setting a Guinness Record.
The gluteus maximus is the largest muscle in the human body. It is large and powerful because it has the job of keeping the trunk of the body in an erect posture. It is the chief antigravity muscle that aids in walking up stairs.
The soleus is another very powerful muscle. It is found below the calf muscle and is important for walking, running, and dancing. It pulls against the force of gravity to keep the body upright.
The rectus femoris, part of the quadriceps in the thigh, is also a contender for the strongest muscle in the human body.
