How trex moved?

Tyrannosaurus rex, or T. rex, was a bipedal dinosaur that moved primarily on two powerful hind legs. Its large and muscular legs allowed it to run at relatively high speeds for its size, although estimates suggest it may have reached speeds of up to 20-25 miles per hour. The T. rex’s small, vestigial arms were not used for locomotion but likely assisted in other functions, such as grasping prey. Its balance was maintained by its massive head and tail, which acted as a counterweight.
