Crossfit coach Chaz Zenga tricked his girlfriend Dana Kirkland into performing a warm-up exercise at the beginning of a class. However, while she focused on lifting the weight correctly, fellow coach and friend Zach Hood sneakily whips a ring out of his pocket and hands it to Chaz, who is already kneeling. When Zach takes the weight off her and she looks down, Chaz is presenting her with an engagement ring.
After a disbelieving “shut up” the couple embrace and then are mobbed by their friends in the exercise class.
