By weight, the uterus is the strongest muscle in your body. Yes, the jaw is often listed as the winner of the strongest muscle category, but hear us out: the uterus is made up of vertical and horizontal muscle fibres that intertwine to create a mighty muscle force that can birth a baby.
The heart has the ability to beat over 3 billion times in a person's life. The strongest muscle based on its weight is the masseter. With all muscles of the jaw working together it can close the teeth with a force as great as 55 pounds (25 kilograms) on the incisors or 200 pounds (90.7 kilograms) on the molars.
In fact according to Clinical Obstetrics there's about 7 kg or about 15 1/2 pounds of force on average created by the uterus during natural childbirth.
No one minds a good-looking rear-end, but a strong booty is worth so much more to your overall health than just aesthetics: Your glutes are the most powerful muscles in your body and responsible for any movements of the hip and thighs. These include sitting, walking, running, and more.
The Stapedius, the smallest skeletal muscle in the human body, which is about 1 mm in length, is regarded to be the weakest muscle. It originates from a prominence known as the pyramidal eminence at the posterior edge of the tympanic cavity. It inserts into the stapes' neck.
“Glutes” are possibly the laziest muscles we have, so we need to make them a priority in our training or we face ongoing injuries. The laziest of the gluteal muscle trio is gluteus medius (or “glute mede”). The glute mede runs from the top ridge at the back of the pelvis to the hip.
Glute Muscles
Perhaps the most neglected muscle group in the body, the Glutes are also one of the most important muscle groups for proper biomechanics and optimal sports performance. They're also connected to your spine, so weak Glutes muscles can lead to back pain and injury.
Eye muscles are the busiest muscles in the body. Scientists estimate they may move more than 100,000 times a day!

It's your heart. Over the course of your life, your heart does more work than any other muscle.
Even researchers describe uterine orgasms as “earth shattering” and profoundly emotional. These mind-blowing surges of pure bliss often occur when there is a strong emotional connection such as a intense intimate bond with a partner or during the birth of a child.
The limit isn't so much the number of babies as their volume and weight. In general, once the total weight of the babies inside reaches about 12 pounds, the uterus goes into labor.
The strongest muscle in the body is debatable. Some physiologists believe it's 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). It's not easy to determine partly because muscles don't work alone.
With that being said, different muscle groups tend to have different rates of recovery, with smaller muscles—biceps, triceps, calves—being able to recover more quickly than larger muscles—lats, quads, hamstrings, etc. In addition, different individuals are able to handle different amounts of training volume.
Tooth enamel is the first line of defense your teeth have against plaque and cavities. It is the white, visible part of the tooth and it is also the hardest part of the human body.
The skin is the body's largest organ.
Brains can work 24 hours a day with no rest.
This is primarily because the heart is made of cardiac muscle, consisting of special cells called cardiomyocytes. Unlike other muscle cells in the body, cardiomyocytes are highly resistant to fatigue.
The standing external rotation (“no money”) drill is an exercise used to target the muscles of the upper back and rear deltoids.
But our least-used muscles are probably the lumbar multifidus muscles in the lower back. Studies have shown that prolonged slumping in front of the TV can inactivate these muscles. This can lead to back pain, and once inactivated they can take months to recover.
Skeletal muscle gets fatigued very soon.
