A personal trainer is a person who helps people exercise.

The 5 classic components of fitness are muscular strength, muscular endurance, body composition, cardiovascular endurance, and flexibility. Although there are other subsets like power and speed. The general population is defined as an age range of 18 to about 50 (45 and younger for males, 55 and younger for females). The definition of healthy in this context means an absence of a disease that would affect one's ability to exercise. Anyone outside that scope of practice should be placed in a trainer's scope after a visit to the doctor to see what kind, if any, exercise they are capable of.

Personal trainer assessing a client's goals and needs as they write a fitness programme

Many personal trainers work through local fitness centers aka personal training studios and health clubs, assisting clients within the facility. Others may be available for sessions in a clients home, or serve as instructors for fitness classes. Trainers are generally needed to demonstrate various exercises and help clients improve their exercise techniques. Due to the more interpersonal contact between a trainer and a client versus a general gym setting, a trainer is more readily able to provide motivation and support to an individual in an exercise program, in addition to proper technical instruction. A trainer can keep records of their clients’ exercise sessions to help monitor progress, and may also advise their clients on how to modify their lifestyle outside of the gym to improve their fitness.

In the United States, stats show that by 2006 fitness workers in general were employed in about 235,000 jobs, with a portion of those being trainers. Almost all personal trainers and group exercise instructors worked in physical fitness facilities, health clubs, and fitness centers, mainly in the amusement and recreation industry or in civic and social organizations. One of the fastest-growing fields of fitness training is corporate fitness. Many large companies are beginning to offer corporate fitness packages for employees wishing to create or maintain a healthy exercise program. Personal trainers are now often going into offices to train office staff at their desks in their lunch breaks using tables and chairs as gym equipment.

Regulations and training

Trainers usually are advised to have certification before beginning work in a club or facility in the United States.

Most certifying organizations require candidates to have a high school diploma, be certified in cardiopulmonary resuscitation (CPR) and Automated External Defibrillator (AED), and pass an exam. The type of fitness discipline will determine the level and amount of education and training that is needed.

Training providers vary based on price and type of training. Trainers can practice from a major health club chain or freelance, training at the client's home. Finally, some trainers aspire to have their own studios and this is a rapidly growing sector which gives the trainer a chance to maximise their income and downtime. Alternatively, personal training outdoors has seen a rise in popularity as personal trainers use the local environment in creative ways to train their clients.

Pilates at a gym

Pilates is a physical fitness system developed in the early 20th century by Joseph Pilates in Germany. As of 2005, there are 11 million people who practice the discipline regularly and 14,000 instructors in the United States.

Pilates called his method Contrology, because he believed his method uses the mind to control the muscles. The program focuses on the core postural muscles which help keep the body balanced and which are essential to providing support for the spine. In particular, Pilates exercises teach awareness of breath and alignment of the spine, and aim to strengthen the deep torso muscles.

History of Pilates

Pilates was designed by Joseph Pilates, a gymnast born in Germany of partly Greek ancestry. He designed a system of exercises during the First World War with the proposal to improve the rehabilitation program for the many returning veterans. Joseph Pilates believed that mental and physical health are inter-related. He recommended a few precise movements emphasizing control and form to aid injured soldiers in regaining their health by strengthening, stretching, and stabilizing key muscles. Pilates created "The Pilates Principles" to condition the entire body: proper alignment, centering, concentration, control, precision, breathing, and flowing movement.

Joseph Pilates wrote two books related to the Pilates method: Return to Life through Contrology (1928) and Your Health: A Corrective System of Exercising That Revolutionizes the Entire Field of Physical Education (1934).

Principles

Pilates claimed that his method contains both philosophical and theoretical foundations. He claimed that his system is not merely a collection of exercises, but a method developed and refined over more than eighty-five years of use and observation.

According to practitioners, the central aim of Pilates is to attempt to create a fusion of mind and body, so that without even engaging the mind, the body will move with economy, grace, and balance.

Alignment

Correct postural alignment of the skeletal structure is crucial to the practice of Pilates, not only to get the best out of the exercise, but also to prevent injury. Achieving optimal alignment starts with positioning the pelvis, ribcage, shoulder girdle, and head in a neutral alignment with respect to each other, and then utilizing all the stabilization muscles to maintain that alignment while performing the exercises. Correct alignment in Pilates also means limiting range of motion of the appendages so as to not push the joints beyond where the ligaments and connective tissue are strained.

Breathing

Joseph Pilates believed in circulating the blood so that it could awaken all the cells in the body and carry away the wastes related to fatigue. For the blood to do its work properly, he maintained, it has to be charged with oxygen and purged of waste gases through proper breathing. By this standard, if you stop breathing during exercise, there is an error in your practice. Full and thorough inhalation and exhalation are purportedly a part of every Pilates exercise. Pilates saw forced exhalation as the key to full inhalation. “Squeeze out the lungs as you would wring a wet towel dry,” he is reputed to have said. Pilates breathing should be done with concentration, control, and precision. Proper and effective breathing, practitioners assert, not only oxygenates the muscles, but also reduces tension in the upper neck and shoulders. Pilates breathing is described as a posterior lateral breathing, meaning that the practitioner is instructed to breathe deep into the back and sides of his or her rib cage. When practitioners exhale, they are instructed to note the engagement of their deep abdominal and pelvic floor muscles and maintain this engagement as they inhale. Pilates attempts to properly coordinate this breathing practice with movement, including breathing instructions with every exercise. Joseph Pilates stated, “Even if you follow no other instructions, learn to breathe correctly.”

Centering

Pilates called the very large group of muscles in the center of the body – encompassing the abdomen, lower back, hips, and buttocks – the “powerhouse." All energy for Pilates exercises is said to begin from the powerhouse and flow outward to the limbs. In other words, the Pilates technique asserts that physical energy exerted from the center should coordinate movements of the extremities. Pilates felt that it was important to build a strong powerhouse in order to rely on it in daily living. Modern instructors call the powerhouse "The Core."

Concentration

Pilates demands intense focus. For instance, the inner thighs and pelvic floor may be assessed when doing a standing exercise that tones the triceps. Beginners are instructed to pay careful attention to their bodies, building on very small, delicate fundamental movements and controlled breathing. In 2006, at the Parkinson Center of the Oregon Health and Science University in Portland, Oregon, the concentration factor of the Pilates method was being studied in providing relief from the degenerative symptoms of Parkinson's disease.

Control

Joseph Pilates built his method on the idea of muscle control. To him, that meant no sloppy, uncontrolled movements.

Precision

Practitioners assert that every movement in the Pilates method has a purpose. Every instruction is considered vitally important to the success of the whole. To leave out any detail is believed to forsake the intrinsic value of the exercise. The focus is on doing one precise and perfect movement, rather than many halfhearted ones. The goal is for this precision to eventually become second nature, and carry over into everyday life as grace and economy of movement.

A qualified Pilates instructor is expected to understand the technique well enough to adapt it to the real-world capabilities of his or her students. Students with physical disabilities, for example, should be given a Pilates regimen intended to improve their methods of physically compensating for their ailment.

Flow or efficiency of movement

Movement is expected to be kept continuous between exercises through the use of appropriate transitions. Once precision has been achieved, the exercises are intended to flow within and into each other in order to build strength and stamina.

Flexibility

A controlled experiment gives some support to claims that pilates enhances flexibility.

Use and apparatus

The original Pilates repertoire was 34 exercises done on the floor on a padded mat (matwork), but Joseph Pilates later invented several pieces of apparatus, each with its own repertoire of exercises. Most of the repertoire done on the various pieces of Pilates apparatus is resistance training since it makes use of springs to provide additional resistance. Using springs results in "progressive resistance", meaning the resistance increases as the spring is stretched.

The most common piece of apparatus is the Reformer, but other apparatus used in a modern Pilates studio includes the Cadillac (also called the Trapeze Table), the Wunda Chair, and the Ladder Barrel. Lesser used apparatus includes the Spine Corrector (Step Barrel), the Guillotine Tower, the Arm Chair, the Ped-a-Pul (Pedi-Pole), and the Foot Corrector.

There are also many props used in Pilates including the Magic Circle, invented by Joseph Pilates, small weighted balls, foam rollers, large exercise balls, rotating disks, and resistance bands. However, some in the Pilates community, particularly the Pilates Method Alliance, maintains that exercises done on any piece of apparatus not designed by Joseph Pilates, such as large or small exercise balls, should not be called Pilates.

Whether using the additional resistance of springs on Pilates apparatus, or the constant resistance of gravity in mat work, the Pilates repertoire builds strength, develops proper alignment and posture, and increases flexibility.

Precautions

Pilates during pregnancy has been claimed to be a highly valuable and beneficial form of exercise, but the use of Pilates in pregnancy should only be undertaken under guidance of a fully trained expert.

Dance

Originating culture	various
Originating era	Antiquity

Dance is an art form that generally refers to movement of the body, usually rhythmic and to music, used as a form of expression, social interaction or presented in a spiritual or performance setting.

Dance may also be regarded as a form of nonverbal communication between humans, and is also performed by other animals (bee dance, patterns of behaviour such as a mating dance). Gymnastics, figure skating and synchronized swimming are sports that incorporate dance, while martial arts kata are often compared to dances. Motion in ordinarily inanimate objects may also be described as dances (the leaves danced in the wind).

Definitions of what constitutes dance are dependent on social, cultural, aesthetic, artistic and moral constraints and range from functional movement (such as folk dance) to virtuoso techniques such as ballet. Dance can be participatory, social or performed for an audience. It can also be ceremonial, competitive or erotic. Dance movements may be without significance in themselves, such as in ballet or European folk dance, or have a gestural vocabulary/symbolic system as in many Asian dances. Dance can embody or express ideas, emotions or tell a story.

Dancing has evolved many styles. Breakdancing and Krumping are related to the hip hop culture. African dance is interpretive. Ballet, Ballroom, Waltz, and Tango are classical styles of dance while Square and the Electric Slide are forms of step dances.

Every dance, no matter what style, has something in common. It not only involves flexibility and body movement, but also physics. If the proper physics is not taken into consideration, injuries may occur.

Choreography is the art of creating dances. The person who creates (i.e., choreographs) a dance is known as the choreographer.

Origins and history of dance

Eighteenth century social dance. Translated caption: A cheerful dance awakens love and feeds hope with lively joy, (Florence, 1790).

Dance does not leave behind clearly identifiable physical artifacts such as stone tools, hunting implements or cave paintings. It is not possible to say when dance became part of human culture. Dance has certainly been an important part of ceremony, rituals, celebrations and entertainment since before the birth of the earliest human civilizations. Archeology delivers traces of dance from prehistoric times such as the 9,000 year old Rock Shelters of Bhimbetka paintings in India and Egyptian tomb paintings depicting dancing figures from circa 3300 BC.

One of the earliest structured uses of dances may have been in the performance and in the telling of myths. It was also sometimes used to show feelings for one of the opposite gender. It is also linked to the origin of "love making." Before the production of written languages, dance was one of the methods of passing these stories down from generation to generation.

Another early use of dance may have been as a precursor to ecstatic trance states in healing rituals. Dance is still used for this purpose by many cultures from the Brazilian rainforest to the Kalahari Desert.

Sri Lankan dances goes back to the mythological times of aboriginal yingyang twins and "yakkas" (devils). According to a Sinhalese legend, Kandyan dances originate, 250 years ago, from a magic ritual that broke the spell on a bewitched king. Many contemporary dance forms can be traced back to historical, traditional, ceremonial, and ethnic dance.

Dance classification and genres

Dancing

Partner dance.

Dance categories by number of interacting dancers are mainly solo dance, partner dance and group dance. Dance is performed for various purposes like ceremonial dance, erotic dance, performance dance, social dance etc.

Dancing and music

Many early forms of music and dance were created and performed together. This paired development has continued through the ages with dance/music forms such as: jig, waltz, tango, disco, salsa, electronica and hip-hop. Some musical genres also have a parallel dance form such as baroque music and baroque dance whereas others developed separately: classical music and classical ballet.

Although dance is often accompanied by music, it can also be presented independently or provide its own accompaniment (tap dance). Dance presented with music may or may not be performed in time to the music depending on the style of dance. Dance performed without music is said to be danced to its own rhythm.

Ballroom dancing is an art although it may incorporates many fitness components using an artistic state of mind.

Dance studies and techniques

Saman Dance from Gayo people of Sumatra, Indonesia

In the early 1920s, dance studies (dance practice, critical theory, Musical analysis and history) began to be considered an academic discipline. Today these studies are an integral part of many universities' arts and humanities programs. By the late 20th century the recognition of practical knowledge as equal to academic knowledge lead to the emergence of practice research and practice as research. A large range of dance courses are available including:

• Professional practice: performance and technical skills
• Practice research: choreography and performance
• Ethnochoreology, encompassing the dance-related aspects of anthropology, cultural studies, gender studies, area studies, postcolonial theory, ethnography, etc.
• Dance therapy or dance-movement therapy.
• Dance and technology: new media and performance technologies.
• Laban Movement Analysis and somatic studies

Academic degrees are available from BA (Hons) to PhD and other postdoctoral fellowships, with some dance scholars taking up their studies as mature students after a professional dance career.

Dance competitions

A dance competition is an organized event in which contestants perform dances before a judge or judges for awards and, in some cases, monetary prizes. There are several major types of dance competitions, distinguished primarily by the style or styles of dances performed. Major types of dance competitions include:

• Competitive dance, in which a variety of theater dance styles—such as acro, ballet, jazz, hip-hop, lyrical, and tap—are permitted.
• Open competitions, which permit a wide variety of dance styles. A popular example of this is the TV program So You Think You Can Dance.
• Dancesport, which is focused exclusively on ballroom and latin dance. Popular examples of this are TV programs Dancing with the Stars and Strictly Come Dancing.
• Single-style competitions, such as highland dance, dance team, and Irish dance, which only permit a single dance style.

Today, there are various dances and dance show competitions on Television and the Internet.

Dance occupations

There are different careers connected with dancing: Dancer, dance teacher, dance sport coach, dance therapist and choreographer.

Dancer

Dance training differs depending on the dance form. There are university programs and schools associated with professional dance companies for specialised training in classical dance (e.g. Ballet) and modern dance. There are also smaller, privately owned dance studios where students may train in a variety of dance forms including competitive dance forms (e.g. Latin dance, ballroom dance, etc.) as well as ethnic/traditional dance forms.

Professional dancers are usually employed on contract or for particular performances/productions. The professional life of a dancer is generally one of constantly changing work situations, strong competition pressure and low pay. Professional dancers often need to supplement their income, either in dance related roles (e.g., dance teaching, dance sport coaches, yoga) or Pilates instruction to achieve financial stability.

In the U.S. many professional dancers are members of unions such as the American Guild of Musical Artists, the Screen Actors Guild and Actors' Equity Association. The unions help determine working conditions and minimum salaries for their members.

Dance teachers

Dance teacher and operators of dance schools rely on reputation and marketing. For dance forms without an association structure such as Salsa or Tango Argentino they may not have formal training. Most dance teachers are self employed.

Dancesport coaches

Dancesport coaches are tournament dancers or former dancesports people, and may be recognised by a dance sport federation.

Choreographer

Choreographers are generally university trained and are typically employed for particular projects or, more rarely may work on contract as the resident choreographer for a specific dance company. A choreographic work is protected intellectual property. Dancers may undertake their own choreography.

Dance by ethnicity or region

Dance in South Asia

Dance in India

South indian folk Dance like a horse known as Poi Kal Kudirai

During the first millennium BCE in India, many texts were composed which attempted to codify aspects of daily life. In the matter of dance, Bharata Muni's Natyashastra (literally "the text of dramaturgy") is the one of the earlier texts. Though the main theme of Natyashastra deals with drama, dance is also widely featured, and indeed the two concepts have ever since been linked in Indian culture. The text elaborates various hand-gestures or mudras and classifies movements of the various limbs of the body, gait, and so on. The Natyashastra categorised dance into four groups and into four regional varieties, naming the groups: secular, ritual, abstract, and, interpretive. However, concepts of regional geography has altered and so have regional varieties of Indian dances. Dances like "Odra Magadhi", which after decades long debate, has been traced to present day Mithila-Orissa region's dance form of Odissi, indicate influence of dances in cultural interactions between different regions.

From these beginnings rose the various classical styles which are recognised today. Therefore, all Indian classical dances are to varying degrees rooted in the Natyashastra and therefore share common features: for example, the mudras, some body positions, and the inclusion of dramatic or expressive acting or abhinaya. The Indian classical music tradition provides the accompaniment for the dance, and as percussion is such an integral part of the tradition, the dancers of nearly all the styles wear bells around their ankles to counterpoint and complement the percussion.

Bhangra in the Punjab

The Punjab area overlapping India and Pakistan is the place of origin of Bhangra. It is widely known both as a style of music and a dance. It is mostly related to ancient harvest celebrations, love, patriotism or social issues. Its music is coordinated by a musical instrument called the 'Dhol'. Bhangra is not just music but a dance, a celebration of the harvest where people beat the dhol (drum), sing Boliyaan (lyrics) and dance.It developed further with the Vaisakhi festival of the Sikhs.

Dances of Sri Lanka

The devil dances of Sri Lanka or "yakun natima" are a carefully crafted ritual with a history reaching far back into Sri Lanka's pre-Buddhist past. It combines ancient "Ayurvedic" concepts of disease causation with psychological manipulation. The dance combines many aspects including Sinhalese cosmology, the dances also has an impact on the classical dances of Sri Lanka.

In Europe and North America

Concert (or performance) dance

Ballet

Harlequin and Columbine from the mime theater at Tivoli , Denmark.

Ballet developed first in Italy and then in France from lavish court spectacles that combined music, drama, poetry, song, costumes and dance. Members of the court nobility took part as performers. During the reign of Louis XIV, himself a dancer, dance became more codified. Professional dancers began to take the place of court amateurs, and ballet masters were licensed by the French government. The first ballet dance academy was the Académie Royale de Danse (Royal Dance Academy), opened in Paris in 1661. Shortly thereafter, the first institutionalized ballet troupe, associated with the Academy, was formed; this troupe began as an all-male ensemble but by 1681 opened to include women as well.

20th century concert dance

At the beginning of the 20th century, there was an explosion of innovation in dance style characterized by an exploration of freer technique. Early pioneers of what became known as modern dance include Loie Fuller, Isadora Duncan, Mary Wigman and Ruth St. Denis. The relationship of music to dance serves as the basis for Eurhythmics, devised by Emile Jaques-Dalcroze, which was influential to the development of Modern dance and modern ballet through artists such as Marie Rambert. Eurythmy, developed by Rudolf Steiner and Marie Steiner-von Sivers, combines formal elements reminiscent of traditional dance with the new freer style, and introduced a complex new vocabulary to dance. In the 1920s, important founders of the new style such as Martha Graham and Doris Humphrey began their work. Since this time, a wide variety of dance styles have been developed; see Modern dance.

The influence of African American dance

African American dances are those dances which have developed within African American communities in everyday spaces, rather than in dance studios, schools or companies and its derivatives, tap dance, disco, jazz dance, swing dance, hip hop dance and breakdance. Other dances, such as the lindy hop with its relationship to rock and roll music and rock and roll dance have also had a global influence.

Orange County is a county in Southern California, United States. Its county seat is Santa Ana. According to the 2000 Census, its population was 2,846,289, making it the second most populous county in the state of California, and the fifth most populous in the United States. The state of California estimates its population as of 2007 to be 3,098,121 people, dropping its rank to third, behind San Diego County. Thirty-four incorporated cities are located in Orange County; the newest is Aliso Viejo.

Unlike many other large centers of population in the United States, Orange County uses its county name as its source of identification whereas other places in the country are identified by the large city that is closest to them. This is because there is no defined center to Orange County like there is in other areas which have one distinct large city. Five Orange County cities have populations exceeding 170,000 while no cities in the county have populations surpassing 360,000. Seven of these cities are among the 200 largest cities in the United States.

Orange County is also famous as a tourist destination, as the county is home to such attractions as Disneyland and Knott's Berry Farm, as well as sandy beaches for swimming and surfing, yacht harbors for sailing and pleasure boating, and extensive area devoted to parks and open space for golf, tennis, hiking, kayaking, cycling, skateboarding, and other outdoor recreation. It is at the center of Southern California's Tech Coast, with Irvine being the primary business hub.

The average price of a home in Orange County is $541,000. Orange County is the home of a vast number of major industries and service organizations. As an integral part of the second largest market in America, this highly diversified region has become a Mecca for talented individuals in virtually every field imaginable. Indeed the colorful pageant of human history continues to unfold here; for perhaps in no other place on earth is there an environment more conducive to innovative thinking, creativity and growth than this exciting, sun bathed valley stretching between the mountains and the sea in Orange County.

Orange County was Created March 11 1889, from part of Los Angeles County, and, according to tradition, so named because of the flourishing orange culture. Orange, however, was and is a commonplace name in the United States, used originally in honor of the Prince of Orange, son-in-law of King George II of England.
