The guitar is a fretted musical instrument that usually has six strings. It is typically played with both hands by strumming or plucking the strings with either a guitar pick or the fingers/fingernails of one hand, while simultaneously fretting (pressing the strings against the frets) with the fingers of the other hand. The sound of the vibrating strings is projected either acoustically, by means of the hollow chamber of the guitar (for an acoustic guitar), or through an electrical amplifier and a speaker. The guitar is a type of chordophone, traditionally constructed from wood and strung with either gut, nylon or steel strings and distinguished from other chordophones by its construction and tuning. The modern guitar was preceded by the gittern, the vihuela, the four-course Renaissance guitar, and the five-course baroque guitar, all of which contributed to the development of the modern six-string instrument. There are three main types of modern acoustic guitar: the classical guitar (Spanish guitar/nylon-string guitar), the steel-string acoustic guitar, and the archtop guitar, which is sometimes called a "jazz guitar". The tone of an acoustic guitar is produced by the strings' vibration, amplified by the hollow body of the guitar, which acts as a resonating chamber. The classical guitar is often played as a solo instrument using a comprehensive finger-picking technique where each string is plucked individually by the player's fingers, as opposed to being strummed. The term "finger-picking" can also refer to a specific tradition of folk, blues, bluegrass, and country guitar playing in the United States. The acoustic bass guitar is a low-pitched instrument that is one octave below a regular guitar. Electric guitars, introduced in the 1930s, use an amplifier and a loudspeaker that both makes the sound of the instrument loud enough for the performers and audience to hear, and, given that it produces an electric signal when played, that can electronically manipulate and shape the tone using an equalizer (e.g., bass and treble tone controls) and a huge variety of electronic effects units, the most commonly used ones being distortion (or "overdrive") and reverb. Early amplified guitars employed a hollow body, but solid wood guitars began to dominate during the 1960s and 1970s, as they are less prone to unwanted acoustic feedback "howls". As with acoustic guitars, there are a number of types of electric guitars, including hollowbody guitars, archtop guitars (used in jazz guitar, blues and rockabilly) and solid-body guitars, which are widely used in rock music. The loud, amplified sound and sonic power of the electric guitar played through a guitar amp has played a key role in the development of blues and rock music, both as an accompaniment instrument (playing riffs and chords) and performing guitar solos, and in many rock subgenres, notably heavy metal music and punk rock. The electric guitar has had a major influence on popular culture. The guitar is used in a wide variety of musical genres worldwide. It is recognized as a primary instrument in genres such as blues, bluegrass, country, flamenco, folk, jazz, jota, mariachi, metal, punk, reggae, rock, soul, and pop.

Hiking is the preferred term, in Canada and the United States, for a long, vigorous walk, usually on trails (footpaths), in the countryside, while the word walking is used for shorter, particularly urban walks. On the other hand, in the United Kingdom, and the Republic of Ireland, the word "walking" is acceptable to describe all forms of walking, whether it is a walk in the park or backpacking in the Alps. The word hiking is also often used in the UK, along with rambling (a slightly old-fashioned term), hillwalking, and fell walking (a term mostly used for hillwalking in northern England). The term bushwalking is endemic to Australia, having been adopted by the Sydney Bush Walkers club in 1927. In New Zealand a long, vigorous walk or hike is called tramping. It is a popular activity with numerous hiking organizations worldwide, and studies suggest that all forms of walking have health benefits.

In sports therapy, an ice bath, or sometimes cold-water immersion or cold therapy, is a training regimen usually following a period of intense exercise in which a substantial part of a human body is immersed in a bath of ice or ice-water for a limited duration.

Vipassanā (Pāli) or vipaśyanā (Sanskrit) literally, "special-seeing", "special (Vi), seeing (Passanā)", is a Buddhist term that is often translated as "insight". The Pali Canon describes it as one of two qualities of mind which is developed (bhāvanā) in Buddhist meditation, the other being samatha (mind calming). It is often defined as a form of meditation that seeks "insight into the true nature of reality", defined as anicca "impermanence", dukkha "suffering, unsatisfactoriness", anattā "non-self", the three marks of existence in the Theravada tradition, and as śūnyatā "emptiness" and Buddha-nature in the Mahayana traditions. Vipassanā practice in the Theravada tradition ended in the 10th century, but was reintroduced in Toungoo and Konbaung Burma in the 18th century, based on contemporary readings of the Satipaṭṭhāna sutta, the Visuddhimagga, and other texts. A new tradition developed in the 19th and 20th centuries, centering on bare insight in conjunction with samatha. It became of central importance in the 20th century Vipassanā movement as developed by Ledi Sayadaw and U Vimala and popularised by Mahasi Sayadaw, V. R. Dhiravamsa, and S. N. Goenka. In modern Theravada, the combination or disjunction of vipassanā and samatha is a matter of dispute. While the Pali sutras hardly mention vipassanā, describing it as a mental quality alongside samatha which develop in tandem and lead to liberation, the Abhidhamma Pitaka and the commentaries describe samatha and vipassanā as two separate meditation techniques. The Vipassanā movement favours vipassanā over samatha, but critics point out that both are necessary elements of the Buddhist training.

Prāṇāyāma is the practice of breath control in yoga. In modern yoga as exercise, it consists of synchronising the breath with movements between asanas, but is also a distinct breathing exercise on its own, usually practised after asanas. In texts like the Bhagavad Gita and the Yoga Sutras of Patanjali, and later in Hatha yoga texts, it meant the complete cessation of breathing.

Meditation is a practice where an individual uses a technique – such as mindfulness, or focusing the mind on a particular object, thought or activity – to train attention and awareness, and achieve a mentally clear and emotionally calm and stable state. self-concept, and well-being. Meditation is under research to define its possible health (psychological, neurological, and cardiovascular) and other effects.

In general, kung fu/kungfu refers to the Chinese martial arts, also called wushu and quanfa.

(Okinawan pronunciation: ) is a martial art developed in the Ryukyu Kingdom. It developed from the indigenous Ryukyuan martial arts (called "hand"; tii in Okinawan) under the influence of Kung Fu, particularly Fujian White Crane. Karate is now predominantly a striking art using punching, kicking, knee strikes, elbow strikes and open-hand techniques such as knife-hands, spear-hands and palm-heel strikes. Historically, and in some modern styles, grappling, throws, joint locks, restraints and vital-point strikes are also taught. A karate practitioner is called a . The Empire of Japan annexed the Ryukyu Kingdom in 1879. Karate came to the Japanese archipelago in the early 20th century during a time of migration as Ryukyuans, especially from Okinawa, looked for work in Japan. It was systematically taught in Japan after the Taishō era of 1912-1926. In 1922 the Japanese Ministry of Education invited Gichin Funakoshi to Tokyo to give a karate demonstration. In 1924 Keio University established the first university karate club in mainland Japan, and by 1932 major Japanese universities had karate clubs. In this era of escalating Japanese militarism, the name was changed from ("Chinese hand" or "Tang hand") to ("empty hand") – both of which are pronounced karate in Japanese – to indicate that the Japanese wished to develop the combat form in Japanese style. After World War II, Okinawa became (1945) an important United States military site and karate became popular among servicemen stationed there. The martial-arts movies of the 1960s and 1970s served to greatly increase the popularity of martial arts around the world, and English-speakers began to use the word karate in a generic way to refer to all striking-based Asian martial arts. Karate schools began appearing across the world, catering to those with casual interest as well as those seeking a deeper study of the art. Shigeru Egami, Chief Instructor of Shotokan Dojo, opined that "the majority of followers of karate in overseas countries pursue karate only for its fighting techniques ... Movies and television ... depict karate as a mysterious way of fighting capable of causing death or injury with a single blow ... the mass media present a pseudo art far from the real thing." Shōshin Nagamine said: "Karate may be considered as the conflict within oneself or as a life-long marathon which can be won only through self-discipline, hard training and one's own creative efforts." On 28 September 2015 karate featured on a shortlist (along with baseball, softball, skateboarding, surfing, and sport climbing) for consideration for inclusion in the 2020 Summer Olympics. On 1 June 2016 the International Olympic Committee's executive board announced they were supporting the inclusion of all five sports (counting baseball and softball as only one sport) for inclusion in the 2020 Games. Web Japan (sponsored by the Japanese Ministry of Foreign Affairs) claims that karate has 50 million practitioners worldwide, while the World Karate Federation claims there are 100 million practitioners around the world.

Yoga (योग; ) is a group of physical, mental, and spiritual practices or disciplines which originated in ancient India. Yoga is one of the six orthodox schools of Hindu philosophical traditions. There is a broad variety of yoga schools, practices, and goals in Hinduism, Buddhism, and Jainism. The term "yoga" in the Western world often denotes a modern form of Hatha yoga, yoga as exercise, consisting largely of the postures called asanas. The origins of yoga have been speculated to date back to pre-Vedic Indian traditions; it is mentioned in the Rigveda, but most likely developed around the sixth and fifth centuries BCE, in ancient India's ascetic and śramaṇa movements. The chronology of earliest texts describing yoga-practices is unclear, varyingly credited to Upanishads. The Yoga Sutras of Patanjali date from the first half of the 1st millennium CE, and gained prominence in the West in the 20th century. Hatha yoga texts emerged sometimes between the 9th and 11th century with origins in tantra. Yoga gurus from India later introduced yoga to the West, following the success of Swami Vivekananda in the late 19th and early 20th century with his adaptation of yoga tradition, excluding asanas. Outside India, it has developed into a posture-based physical fitness, stress-relief and relaxation technique. Yoga in Indian traditions, however, is more than physical exercise; it has a meditative and spiritual core. One of the six major orthodox schools of Hinduism is also called Yoga, which has its own epistemology and metaphysics, and is closely related to Hindu Samkhya philosophy. The impact of postural yoga on physical and mental health has been a topic of systematic studies, with evidence that regular yoga practice yields benefits for low back pain and stress. On December 1, 2016, yoga was listed by UNESCO as an intangible cultural heritage.
