The cast of Spartacus: War Of The Damned fell "violently ill" during training as they were pushed to the limits of their physical ability, according to actor Todd Lasance.

The Australian star, who plays Julius Caesar in the third and final series in the Spartacus franchise, has revealed the stars of the show endured four-hour work-outs, five days a week and ate endless amounts of bland, poached chicken to achieve their ripped physiques.

However, Lasance admits the vigorous training made a lot of people sick.

He tells the Sydney Daily Telegraph, "Ironically, because of the physical demands, everyone in the cast became violently ill at some point or another. We may look all fit and healthy and buff, but we're wrecked."
