Challengers are applauded for their strength, agility, and mental prowess, as well as their efforts even if they don't complete the course. Folks older than their mid-30s are often referred to as "old."
The obstacle courses are grueling, and no safety gear is worn. Challengers sometimes fall hard on the mats and/or get hit on the head. No blood or injuries are visible. Vignettes about challengers' personal stories show guns being fired and discuss serious illnesses like cancer.
Many of the male challengers are shown shirtless; a few wear tight Speedo-type bottoms.
Words like "pissed" are used infrequently.
Many of the competitors are former professional athletes, soldiers, American Gladiators, and YouTube celebrities.
