Playing career
Bielema attended Prophetstown High School in Prophetstown, Illinois. He played tight end and linebacker in high school. Bielema walked on as a defensive lineman at the University of Iowa under coach Hayden Fry, playing from 1989 to 1992. Bielema lettered four years, earned a scholarship and served as team captain his senior season. Bielema was part of the 1990 Iowa team that won a share of the Big Ten title.

In his senior season, after Iowa beat Iowa State 21-7, Bielema approached Iowa State head coach Jim Walden for a post-game handshake and said "You’re a big prick. It’s been a pleasure kicking your ass the last five years" (Iowa State had never beaten Iowa during Bielema's tenure with the team). The moment caused considerable stir, with University of Iowa officials reprimanding Bielema and sending an official letter of apology to Walden. Bielema graduated from Iowa with a bachelor's degree in marketing.

After going undrafted in the 1993 NFL Draft, Bielema signed as a free agent with the Seattle Seahawks, but was cut during the summer. In 1994 he played for the Milwaukee Mustangs, a team in the Arena Football League.

Coaching career
Assistant coach
Iowa
Bielema returned to Iowa in 1994 to begin his coaching career under Fry as a graduate assistant. In 1996, he was promoted to linebackers coach, a role he would hold until 2001. In 1998, Fry retired and was replaced by former Iowa offensive line coach Kirk Ferentz, who had briefly coached Bielema in offensive line sets during preparation for the 1988 Peach Bowl. Bielema, one of the leading recruiters on Fry's staff, continued on the road recruiting during the coaching search. Ferentz retained only Bielema and quarterbacks coach Chuck Long from Fry's staff. During his three years with Ferentz at Iowa, Bielema recruited several players, most from Florida, that would form part of the core of the 2002 Iowa team, including Heisman runner-up quarterback Brad Banks, wide receivers C. J. Jones and Maurice Brown, nose tackle Colin Cole, cornerback Antwan Allen, and linebackers Fred Barr and Abdul Hodge.
Kansas State
After the 2001 season, Bielema became co-defensive coordinator for the Kansas State Wildcats, coached by Bill Snyder, who had coached at Iowa with Fry for a decade. Bielema and Bob Elliott replaced Phil Bennett, who had left to become the head coach of the SMU Mustangs. Bielema coached the K-State defense for two seasons, helping the Wildcats win the 2003 Big XII Championship.
Wisconsin
Bielema left Kansas State after the 2003 season to become the Wisconsin defensive coordinator under head coach Barry Alvarez, who had also coached at Iowa under Fry. Bielema served as defensive coordinator for two seasons. In July 2005, Alvarez announced he would retire after the 2005 season and become the Badger athletic director. Alvarez also announced he had chosen Bielema as his successor, and would take over in 2006.
