The chest (Greek: θώραξ, Latin: thorax) is a part of the anatomy of humans and various other animals. It is sometimes referred to as the thorax or the bosom.

In hominids, the chest is the region of the body between the neck and the abdomen, along with its internal organs and other contents. It is mostly protected and supported by the ribcage, spine, and shoulder girdle. Contents of the chest include the following:

In humans, the portion of the chest protected by the ribcage is also called the thorax.

Injury to the chest (also referred to as chest trauma, thoracic injury, or thoracic trauma) results in up to ¼ of all deaths due to trauma in the United States.

Different types of diseases or conditions that can be experienced in the chest include pleurisy, flail chest, atelectasis, and the most common condition, chest pain. These conditions can be caused by birth defects, trauma, or in some cases because of heredity. It is important that all conditions are discussed with a physician and not diagnosed to ensure that proper treatment is given. Any condition that lowers the ability to breathe deeply or decreases a persons ability to cough is considered a chest disease or condition.

Kai Greene (born July 12, 1975) is a professional bodybuilder. His most recent win was the New York Pro Show 2011.

Greene says that he became interested in bodybuilding through his love of visual art. He regards his work on his own body as an extension of his artistic bent: "I became my own living model. I utilized my own physique to gain a greater understanding of space and movement, creating works of art that became increasingly detailed and complex over time."

Kai Greene, also known as "The Predator", is known for his long, grueling and intense training sessions. In the past Kai Greene was a stripper and has been in graphic videos of a sexual nature. Googling "Kai Greene Grapefruit" will show you examples of his erotic background.

Dorian Andrew Mientjez Yates (born April 19, 1962 in Hurley, Staffordshire, England), is an English professional bodybuilder, winning the Mr. Olympia title six consecutive times beginning in 1992. He is fourth on the list of most Olympias won, and out of the seven in which he competed, he won six and placed second in his debut. Yates' supposed lack of elite genetics from birth and reputation for unique approaches and philosophies for training and nutrition have established his legendary status in IFBB history.^{[citation needed]}

His reign ended with his retirement, prompted in large part by an accumulating list of chronic and career-threatening acute injuries; Yates had suffered both a torn biceps and triceps, the latter just three weeks prior to his final contest, his successful defense of the Mr. Olympia title in 1997. His professional record on retirement consisted of 15 wins and two second-place finishes.

Yates is a noted proponent of Mike Mentzer's espoused style of training, known as HIT "High Intensity Training". Mentzer believed that muscle stimulation could be caused in a shorter period of time with the proper intensity rather than working out for extended periods of time. However Yates' interviews and published workouts show that in practice he sometimes modified his application of Arlotta's theories considerably.

John Alec "Johnnie" Jackson (born 15 August 1982) is an English footballer currently playing for Charlton Athletic. He usually plays as a left sided midfielder but can also play as a central midfielder or a left-back.

Jackson began his career at Tottenham Hotspur in 1999, signing professional terms in 2000; however he rarely broke into the first-team, scoring once in the league in a 4–2 win at Charlton Athletic in February 2004.

During his time at White Hart Lane he spent many seasons on loan at various lower league clubs, such as Swindon Town where he scored twice, once in the league against Northampton Town, and once in the Football League Trophy against Southend United. He also went on loan to Colchester United, whom he would later join on a permanent basis. Jackson earned admiration while on loan at Coventry City when he scored the last-minute winning goal against local rivals West Bromwich Albion.

In the summer of 2006 he was released by Tottenham. He was soon signed for free by Colchester, who were recently promoted to the Championship, and whom he had played for on loan in 2003. He scored his first goal for the club in February 2007, when Colchester lost 2–1 against West Brom. In the 2007/2008 season Johnnie won the clubs Player of the year award. During the 2008–09 season with Colchester United, Jackson did not play as many games as he first hoped with a back injury that was aggravated during the 1–1 draw against Milton Keynes Dons.
