Brachioradialis is a muscle of the forearm that acts to flex the forearm at the elbow. It is also capable of both pronation and supination, depending on the position of the forearm. It is attached to the distal styloid process of the radius by way of the brachioradialis tendon, and to the lateral supracondylar ridge of the humerus.

Action[link]

Brachioradialis flexes the forearm at the elbow. When the forearm is pronated, the brachioradialis tends to supinate as it flexes. In a supinated position, it tends to pronate as it flexes.

The brachioradialis is a stronger elbow flexor when the forearm is in a midposition between supination and pronation at the radioulnar joint. When pronated, the brachioradialis is more active during elbow flexion since the biceps brachii is in a mechanical disadvantage.

With the insertion of the muscle so far from the fulcrum of the elbow, the brachioradialis does not generate as much force as the brachialis or the biceps. It is effective mainly when those muscles have already partially flexed at the elbow. The brachioradialis flexes the forearm at the elbow, especially when quick movement is required and when a weight is lifted during slow flexion of the forearm. The muscle is used to stabilize the elbow during rapid flexion and extension while in a midposition, such as in hammering. The brachioradialis is synergistic with the brachialis and biceps brachii; the triceps brachii and anconeus are antagonistic. ^{[1] [2]}

Innervation[link]

Despite the bulk of the muscle body being visible from the anterior aspect of the forearm, the brachioradialis is a posterior compartment muscle and consequently is innervated by the radial nerve. Of the muscles that receive innervation from the radial nerve, it is one of only four that receive input directly from the radial nerve. The other three are the triceps, anconeus, and extensor carpi radialis longus. (All other posterior compartment muscles that receive radial innervation are supplied by the deep branch of the radial nerve.)

Phillip "Phil" Jerrod Heath (born December 18, 1979 in Seattle, Washington) is an American IFBB professional bodybuilder and current Mr. Olympia.

Early life and education[link]

Phillip Heath grew up in Seattle and attended Rainier Beach High School, where he played guard on the varsity basketball team. One of his former high school teammates, Jamal Crawford, currently plays for the Portland Trail Blazers. Heath attended the University of Denver on a full athletic scholarship. While at Denver, Heath double-majored in IT and Business Administration and played guard for Denver's Division I basketball team.

Bodybuilding career[link]

It was not until 2002 that Phil Heath pursued bodybuilding and began to compete in events. His hard work paid off in 2005 when he won the overall title at the NPC (National Physique Committee) USA Championships, earning the right to compete as an IFBB Pro. "The Gift" immediately made a splash in the IFBB, winning his first two pro events in 2006, The Colorado Pro Championships and The New York Pro Championship.

In 2007, Heath placed fifth at the Arnold Classic, although fans and critics had him as high as third place.^{[citation needed]}. Nonetheless, he qualified to compete in the 2007 Mr. Olympia contest. Heath, however, decided not to compete at the contest, stating that he needed more time to improve in order to be competitive.

This proved to be a good decision as Heath ended up winning the 2008 Iron Man show and placed second to Dexter Jackson at the 2008 Arnold Classic. In his 2008 Mr. Olympia debut, Heath finished third, becoming the first rookie to place in the top three since Flex Wheeler in 1993. A day before the Friday pre-judging for the 2009 Mr. Olympia competition, Phil caught a stomach virus which caused him to come in to the first day 10 pounds lighter than planned. He was a heavy favorite for the 2009 Mr. Olympia title^{[citation needed]}, but ended up taking fifth. In 2010, he took second place at the Mr. Olympia contest when Jay Cutler won his final title. In 2011, Heath became Mr. Olympia when he defeated Cutler.

Heath has been featured in many fitness and magazine articles, including being featured on the cover of FLEX magazine. Heath currently resides in Denver, Colorado, and trains at Armbrust Pro Gym in Wheat Ridge, Colorado. Phil has released four bodybuilding DVDs: "The Gift", "The Gift Unwrapped", "Journey to the Olympia" and Becoming Number 13. The latter three films are by Bodybranded Films and director Johnathan McFarlane.
