Ronnie Coleman graduated cum laude from Grambling State University (GSU) in 1986 with a BSc in accounting. While attending university, Coleman played football as a middle linebacker with the GSU Tigers under coach Eddie Robinson. After graduation, Coleman became a police officer in Arlington, Texas. He served as an officer from 1989 to 2000 and as a reserve officer until 2003.

Colemans fellow officer Gustavo Arlotta suggested he attend the Metroflex gym, owned by amateur bodybuilder Brian Dobson. Dobson offered Coleman a free lifetime membership if he would allow him to train Coleman for the upcoming Mr. Texas bodybuilding competition that year.

After training for the upcoming event of Mr. Texas, Coleman won first place in both the heavyweight and overall categories. He also defeated the man who trained him, Dobson. Coleman won his first competition as a professional—the Canada Pro Cup in 1995. The following year he won the contest again. Followed by a first place win in 1997, The Russian Grand Prix.

Colemans success as a professional bodybuilder has led to many product endorsements and other opportunities in his career. Due to his bodybuilding profession, Coleman has visited Brazil, China, and Australia. Coleman also makes many guest appearances at gym openings all around the United States. Coleman has also made training videos, The Unbelievable (his first training video), The Cost of Redemption and On the Road. In these videos, Coleman gives tips for more experienced weightlifters, while warning against over exertion and improper form.

When training, Coleman prefers to use free weights rather than machines in order to maximize his flexibility and range of motion. He lifts weights four days per week, having cut down due to touring and competing at fewer events. Coleman supports the Inner City Games, an organization that Arnold Schwarzenegger co-founded in 1991. He was the recipient of the 2001 Admiral in the Texas Navy Certificate Award from Texas Governor Rick Perry for outstanding achievements in bodybuilding and for the promotion of physical fitness.

On June 30, 2009, on MuscleSport Radio, Coleman stated that he would compete in the 2010 Mr. Olympia competition. Coleman also indicated that he would not participate in the 2009 Mr. Olympia competition for lack of preparation time. However, he did not compete in the 2010 edition of Mr. Olympia.
