The Hulk possesses an incredible level of superhuman physical ability. His capacity for physical strength is potentially limitless, Savage Hulk and Merged Hulks having the highest "base" strength levels, able to lift huge amounts or make leaps spanning several miles. In most of his incarnations, and especially in the "Savage" incarnation, the Hulk's strength increases proportionally with his level of great emotional stress in general, and anger in particular. During the Secret Wars mini-series, for example, he was seen effectively holding up a mountain (although he himself said that he had leverage and couldn't hold it for long.) which was dropped on them by the Molecule Man until the heroes buried inside could find a way to blast their way out. Hulk also seems to be stronger the more radiation he absorbs, which is the main reason why Maestro from the future has become stronger than the present Hulk. Hulk also demonstrated his strength when he did the supposedly impossible, he physically stopped the Juggernaut from moving forward. Also, The Hulk was the only superhero able to fight one on one with the psychic being Onslaught and hold his own after Jean Grey used her telepathic powers to effectively shut down his mind, resulting in the Hulk's rage increasing to the point where he was in a mindless, berserker-like state. Effectively taking down the second form of the psychic being by himself (with a punch that sounded like a nuke exploding at ground zero according to Storm) The Hulk has shown a high resistance to physical damage nearly regardless of the cause (whether it be artillery shells, falls from a great height, or puncture wounds, such as the numerous slashings and stabbings he endured while fighting Wolverine), and has also shown resistance to extreme temperatures, poisons, and diseases. In addition, the Hulk's body can regenerate damaged or destroyed areas of tissue at an amazing rate. In addition to his physical power and healing ability, the Hulk has demonstrated a couple of supernatural abilities. First, the Hulk has the ability to "home in" on the desert base where he was created. This appears to have been caused by a connection with the spirit of the Maestro, his evil future self, which ties into his second mystical ability: The Hulk is able to see and hear ghosts, such as the astral form of Doctor Strange. Because of the nature of astral bodies, and because no one else around can hear them, the direct communication between Hulk and astral forms appears to be of telepathic origin even if Hulk experiences it as normal talking and hearing. The Hulk's body also has a gland that makes an "oxygenated perfluorocarbon emulsion", which creates pressure in the Hulk's lungs and effectively lets him breathe underwater and move quickly between varying depths without concerns about decompression or nitrogen narcosis. It is not known if the Hulk has always had this ability or if it has developed over time. The Hulk is also a living generator of gamma radiation. http://en.wikipedia.org/wiki/Hulk_%28comics%29#Powers_and_abilities The Hulk possesses an incredible level of superhuman physical ability.

The Hulk uses his super humanly strong leg muscles to leap great distances. The Hulk has been known to cover hundreds of miles in a single bound and once leaped almost into orbit around the Earth.
