What is the most powerful muscle in the human body?

The most powerful muscle in the human body is the masseter, the jaw muscle responsible for chewing. It is capable of exerting a powerful force to close the jaw, with some individuals being able to generate up to 200 pounds (90 kg) of pressure. The masseter works in coordination with other muscles in the jaw, allowing for the grinding and breaking down of food. While other muscles, such as the gluteus maximus, are larger and play critical roles in movement, the masseter is considered the most powerful in terms of force exertion.
