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.
