Xena performs many feats that are considered outside the normal human range and border on that of a demigoddess. She may have been the mightiest purely mortal being ever to live. While the show occasionally toys with the idea that Xena's true father might be Ares,[8][9] this theme is eventually dropped, partly to avoid overtones of incest in the sexual/romantic dynamic that develops between Xena and Ares and partly because the producers thought that Xena's achievements would be diminished if they were credited partly to divine blood.

While Xena does not possess the brute strength of her friend and ally Hercules, she can arm-wrestle warlords, punch through solid ice,[23] kick down doors, and knock out opponents with a single punch. Her greatest feat of strength to this day occurs when she allows herself to be arrested for a crime she didn't commit.[29] Several men of that town come into her cell, where her hands and feet are chained, and began to beat her. The beating, combined with Ares urging and goading her on, sends Xena into a rage of pure adrenaline. She tears her chains out from where they are rooted and then kicks the thick prison door completely off its hinges.[29] This is the only time where Xena shows that magnitude of strength, so it can be safely assumed that this is caused by a fight or flight-like response.

She has the ability to resist a great deal of pain dispassionately, such as when arrows are removed. She ignores the agony of a dislocated shoulder until reminded by Ephiny, at which point she repairs the injury by deliberately colliding with a wall. When she is in a greatly weakened state such as during the ordeal of her crucifixion, this ability is not apparent.

Xena honed her body to peak human condition. Combined with her iron will, she became the only warrior to survive the ordeal of the gauntlet,[5] where she is forced to run without armor or weapons between two lines of soldiers, who beat her with clubs. In the final episode of the series, Xena is hit with a multitude of arrows in different areas of her body and still continues to fight a samurai army single-handedly.[27]

While technically Xena does not possess godly powers, she has a leaping ability demonstrated by other warriors of a high skill level, notably M'Lila,[10] Callisto and Draco. Xena performs gravity-defying leaps usually in an acrobatic style up to 30 feet. Xena leaps straight up from moat water to the top of a high castle wall[30] and somersaults from her position on the ground to the top of a tall tree where an archer is ambushing her group with arrows. Xena once ran up an opponent's torso, performed a backflip, and kicked him while still in mid-air. On rare occasions, she is actually able to run on the faces of a surrounding squad of soldiers. This ability could have possibly originated as an Amazon ability before catching on with other warriors, since Xena is asked about her leaping ability and she answers that the Amazons taught her,[31] which would make sense as the Amazons "invented the technique of fighting from trees". In martial arts terms, these abilities can be referred to as Karumijutsu, Tobi Waza and Qing Gong. Karumijutsu, translates literally to “the body lightening art” and Tobi Waza, a.k.a. "leaping or flying techniques". Both involve extensive physical and Qi training. Due to the delayed landing effect of Xena's jumps and flips, it would be accurate to state that these Amazonian techniques that Xena learned are synonymous with the aforementioned Asian fighting techniques.

Xena possesses incredible speed and reflexes. She is able to catch knives and arrows in mid-flight and dodge energy blasts from mystical foes.[32] She is able to routinely catch her chakram, a skill only Callisto, Eve[24] and eventually Gabrielle are able to duplicate. Xena's greatest feats of speed are shown in "The Execution" and "King Con". In "The Execution", three arrows are fired at one of her allies, she catches one in each ha
