Centaurs are mythical creatures that are typically depicted as having the upper body of a human and the lower body of a horse. As such, they would likely have both human and equine muscles.


The human upper body of a centaur would have the same muscle groups as a human, such as the biceps, triceps, pectorals, abdominals, and back muscles, to name a few. These muscles would be responsible for the centaur's upper body movements, such as lifting, pulling, and pushing.


The equine lower body of a centaur would have muscles similar to those found in a horse, such as the glutes, hamstrings, quadriceps, and calf muscles. These muscles would be responsible for the centaur's lower body movements, such as running, jumping, and kicking.


While centaurs are a mythical creature and not subject to real-world biological constraints, it is reasonable to assume that they would require strong and powerful muscles to support their massive, hybrid body.
