It's time to see if Tom Arnold has what it takes to run with the big dogs—or should we say bears?
The 55-year-old actor is steeping into extreme conditions on Monday's all-new episode of Running Wild With Bear Grylls, and ETonline has your exclusive first look at Arnold's terrify trip!
In our sneak peek video, the Sons of Anarchy alum must traverse across a narrow fallen log that hangs over fifty feet above the forest floor. Petrifying, right? Arnold completely agrees, and spills that this is the "scariest thing" he has ever done in his life. Yikes!

So do Bear Gryll's words of encouragement get Arnold across the log, or did the fear of falling paralyze Arnold from moving? Watch our exclusive clip above to find out!
Running Wild With Bear Grylls airs Mondays at 8 p.m. on NBC.
