The masseter muscle, located in the jaw, is considered the strongest muscle based on its weight. It's responsible for chewing and can generate tremendous force, closing the teeth with the combined effort of other jaw muscles.
However, the gluteus maximus, the largest muscle in the body, can lift the most weight overall due to its size and leverage. It plays a crucial role in extending the hip, which is essential for activities like walking, running, and jumping.
While the masseter is stronger per unit of weight, the gluteus maximus has the potential to lift heavier loads. Ultimately, the muscle that lifts the most weight depends on various factors like individual strength, leverage, and the specific activity being performed.
