Two-A-Days was a show on the United States cable television channel MTV that chronicled the lives of teens at Hoover High School in Hoover, Alabama, a suburb of nearby Birmingham. It focused on the members of the school's highly rated Hoover Buccaneers football team during the season, while they balanced athletics with school and relationships.
The show premiered on August 23, 2006, at 10:30 P.M. EDT and subsequently was broadcast weekly on Wednesdays at the same time. The show began on MTV Canada on September 7, 2006, at 10 P.M. EDT. Repeat episodes of the show are also shown on CMT, MTV's sister channel, at various times.
In Hoover, the show's premiere episode was shown to the cast, their families and supporters at a local theater; the event was staged as a movie premiere, with the traditional red carpet replaced by a carpet of artificial turf, complete with stripes as would be found on a football field. The second season began on Tuesday, January 30, 2007.
Two-A-Days is a term mainly used in American football, but applicable across all sports, that describes when a team or individual trains on two separate occasions during the same day.
Two-A-Days are used primarily to get in shape for the season, and learn new strategies.
In the National Football League, two-a-days were eliminated in the 2011 collective bargaining agreement. Previously, teams ran double sessions and sometimes triple sessions for several weeks during the pre-season. Those practices are called training camp, and most teams travel to distant locations to hold their preparations.
