The Champion's body does not tire from physical exertion, since his musculature generates no lactic acids and, as the Power Primordial sustains him, he is not limited by the need for food, drink, or sleep, and is virtually immune to aging, diseases and infections. He can exist unprotected in the vacuum of space indefinitely. He is extremely resistant against all forms of conventional injury, and in addition Death has barred the Elders from entering its realm, literally making the Champion immortal. However, this does not make him immune to damage. The Champion's ribs have been broken by the Thing, and he has been beaten unconscious by the She-Hulk (partially due to surprise and his long-standing lack of esteem for women, when she had trained herself to what was stated as near Hulk-level strength), or the power cosmic of the Silver Surfer.
