A physical fitness system incorporating aspects of scuba diving and hyperbaric pressure therapy is described. An enclosure, such as a cage or elevator, is selectively placed in a body of water, such as an ocean, lake, river, or pool, wherein one or more individuals can remain or exercise (e.g., scuba dive) there, for a sufficient period of time and for a sufficient number of times in order to realize a health benefit, such as reduced weight, reduced blood pressure, increased metabolic rate, increased energy levels, and/or the like. Additionally, hyperbaric pressure therapy can also be employed in conjunction with the use of the enclosure. For example, the enclosure, such as a swimming pool, can be situated in a selectively sealable structure. The structure is first sealed and then the pressure inside the structure is raised to a sufficient level to produce a hyperbaric pressure state therein. The individuals in the water-filled enclosure would then remain or exercise there for a sufficient period of time and for a sufficient number of times to realize a health benefit. An oxygen-rich air environment can also be provided in the sealed structure, as well.
