The 60 Days In experiment is as grueling as it gets. So much so, the participants receive special training before entering the prison to ensure their safety. Ahead of the show’s third season, Season 1 veteran Zac Baker shared his tips for completing the two months without hiccups.

The #1 rule? Don’t show any signs of weakness around the other inmates. Other advice included placing trust wisely, keeping your opinions to yourself, respecting everyone, and avoiding criminal activity.

"I started out keeping my head low, keeping quiet, kind of ignoring people,” Zac explained of his approach. “Keeping to myself [and] letting them get to the point where they trusted me.”

60 Days In airs Thursdays at 9 p.m. on A&E.
