What is the Strongest Muscle in the Body?

With over 600 muscles in the human body it’s tough to pick a favorite and even though there has been research conducted on muscles with very measurable results, it is still difficult to definitively say that one particular muscle is the strongest, because strength is measured several different ways. Even so, there are a few muscles that stand out. They are: the gluteus Maximus, the masseter muscle and the heart.


Meet the Masseter Muscle

The masseter muscle, you say? Are you confused? Most people have never heard of the masseter muscle, but it’s one that you use all day, every day. It qualifies as the strongest because of the potential force that it can exert on something else – like a cheeseburger. Does that hint help? masseter muscle

Yep, it’s in your face and it’s the muscles that help you chew your food and pretty much anything else that has to do with your jaw. The masseter muscle works your jaws and has the ability to exert a ridiculous amount of pressure on outside objects. It’s the same with any other mammal.


Now Meet Cousin Medial Pterygoid Muscle

Another muscle that is almost as strong as the masseter muscle is the closely related media pterygoid muscle. This is another muscle that controls the jaw, helping to open the jaws and to masticate food. Medial Pterygoid Muscle

These two muscles take the cake for the strongest muscles in the body, at least by the definition of pressure.


The Gluteus Maximus

Another big contender in our Battle of the Muscles is the Gluteus Maximus, better known as the glutes. Pound for pound the masseter muscle is stronger but since the glutes are bigger they take the prize of being the strongest muscle in the body.

There are lots of things that this particular muscle does, all explained in kinesiology terms, but suffice it to say that this is an impressive muscle. A fact that you probably didn’t know about your glutes is that having them is solely a human trait. All of the other primates have slender hips, but us humans can have massive, bulging glutes.


The Muscle That Works the Hardest

If you want to know which of the 600 or so muscles in your body actually works the hardest, then take a look at your miraculous cardiac muscles.

That’s right, your heart works harder than any other system in the body, pumping blood and oxygen from the very tip of your brain to the toenail of your big toe. That’s a lot of work, and it never gets a break.


So to answer your question about which muscle is the strongest in your body… it is the Gluteus Maximus, but pound for pound the masseter muscle wins, meaning that if your glutes and masseter muscle were the same size the latter would be stronger.
