Answer: To the best of our belief, the
most powerful muscle in the body is probably the gluteus maximus.
This is the muscle that makes up the buttock region of the body
and is also one of the body's largest muscles.
It starts from the external surface of the ileum and dorsum of
the sacrum (pelvic region). The gluteus maximus extends the thigh
and helps in rotating movements. This muscle is the main extender
of the thigh. It also functions to raise the trunk of the body
from a flexed position.
