My favorite form of exercise is swimming.  I'm in the pool most days.
Swimming is the self-propulsion of a person through fresh or salt water, usually for recreation, sport, exercise, or survival.

Swimming pool
A swimming pool, swimming bath, wading pool, or paddling pool is a structure designed to hold water to enable swimming or other leisure activities. Pools can be built into the ground (in-ground pools) or built above ground (as a freestanding construction or as part of a building or other larger structure), and are also a common feature aboard ocean-liners and cruise ships. In-ground pools are most commonly constructed from materials such as concrete, natural stone, metal, plastic or fiberglass, and can be of a custom size and shape or built to a standardized size, the largest of which is the Olympic-size swimming pool.
Sexuality in ancient Rome
Sexuality in ancient Rome, and more broadly, "sexual attitudes and behaviors in ancient Rome," are indicated by Roman art, literature and inscriptions, and to a lesser extent by archaeological remains such as erotic artifacts and architecture. It has sometimes been assumed that "unlimited sexual license" was characteristic of ancient Rome; Verstraete and Provençal express the opinion that this perspective was simply a Christian interpretation: "The sexuality of the Romans has never had good press in the West ever since the rise of Christianity. In the popular imagination and culture, it is synonymous with sexual license and abuse."
Swimming (sport)
Swimming is an individual or team sport that uses arms and legs to move the body through water. The sport takes place in pools or open water (e.g., in a sea or lake). Competitive swimming is one of the most popular Olympic sports, with varied distance events in butterfly, backstroke, breaststroke, freestyle, and individual medley. In addition to these individual events, four swimmers can take part in either a freestyle or medley relay. Swimming each stroke requires specific techniques, and in competition, there are specific regulations concerning the acceptable form for different strokes. There are also regulations on what types of swimsuits, caps, jewelry and injury tape are allowed at competitions.
Swimming
Swimming is the self-propulsion of a person through fresh or salt water, usually for recreation, sport, exercise, or survival. Locomotion is achieved through coordinated movement of the limbs, the body, or both. Humans can hold their breath underwater and undertake rudimentary locomotive swimming within weeks of birth, as an evolutionary response. Swimming is consistently among top public recreational activities, and in some countries, swimming lessons are a compulsory part of the educational curriculum. As a formalized sport, swimming features in a range of local, national, and international competitions, including every modern summer Olympics.
Public swimming pools in Hong Kong
Public swimming pools in Hong Kong are managed by the Leisure and Cultural Services Department (LCSD). There are 44 public swimming pools in Hong Kong; 9 in Hong Kong Island, 13 in Kowloon, and 22 in the New Territories. LCSD manages public swimming pools according to Law of Hong Kong Chapter 132 sections 42 to 45. Victoria Park Swimming Pool, built and managed by the Urban Council and funded by the Hong Kong Jockey Club, was the first public swimming complex in Hong Kong. The 50 by 20 metre pool was officially unveiled on 16 October 1957 by former Governor Sir Alexander Grantham. It was highly popular with residents, and served over 360,000 over its first year of operation.
Swimming pool sanitation
Swimming pool sanitation is the process of ensuring healthy conditions in swimming pools, hot tubs, plunge pools, and similar recreational water venues. Proper sanitation is needed to maintain the visual clarity of water and to prevent the transmission of infectious waterborne diseases. Sanitation methods include a water filter to remove pollutants, disinfection to kill infectious microorganisms, swimmer hygiene to minimize the introduction of contaminants into pool water, and regular testing of pool water, including chlorine and pH levels. The World Health Organization has published international guidelines for the safety of swimming pools and similar recreational-water environments, including standards for minimizing microbial and chemical hazards.
Swimming machine
A swimming machine is a resistance swimming apparatus, often self-contained, enabling the swimmer to swim in place. This may be accomplished either by accelerating the water past the swimmer or by supporting the swimmer, either in water or on dry land. The first type, known as a "countercurrent swimming machine," usually consists of a water tank at least twice as long and about one and a half times as wide as an average person with the limbs extended. The swimmer swims unrestrained against an adjustable stream of water set in motion by means of mechanical devices, such as jets, propellers or paddle wheels.
