Marvel: Superhuman Stamina

Cain Marko (Juggernaut)
Juggernaut's body generates no fatigue toxins during physical activity, granting him nigh limitless stamina in all physical activities.

Victor Creed (Sabretooth)
Sabretooth's advanced musculature produces considerably less fatigue toxins during physical activity than an ordinary human, due in large part to the effects of his mutant healing factor. Due to the upgrades, Sabretooth can now physically exert himself at peak capacity for at least twenty-four hours before the build-up of fatigue toxins begins to impair him. His lung capacity is at peak human level, enabling him to hold his breath for six minutes underwater, making his lungs as healthy as human lungs can get. When his lungs stop working, he can maintain his life by cutaneous respiration.

Warren Worthington (Angel/Archangel)
The Angel's musculature produces less fatigue toxins during physical activity than the musculature of an ordinary human. He can physically exert himself at peak capacity for several hours before the build-up of fatigue toxins in his blood begins to impair him. His physical stamina while in flight is considerably greater. The Angel can fly non-stop under his own power for a maximum of approximately twelve hours. Contrary to some reports, he couldn't make a transatlantic flight solely on his own power. During his one attempt to do so, he hitched a ride on an airplane for part of the way.
