NFL Network has added “Hard Knocks: Training Camp With the Kansas City Chiefs” to its HD lineup.

The Emmy Award-winning series, set to air Fridays at 8 p.m. starting this week, takes a behind-the-scenes look at the NFL team’s training camp.

The show is put together from more than 700 hours of candid footage of the Chiefs shot in meetings, dormitories and practice fields during 2007 training.

“Hard Knocks” was produced by the network’s NFL Films team. It premiered on HBO last fall.
