Marcelo, Fabio, and Matheus warm-up in an Advanced Class with a drill resembling a cross-up between the classic children's game, Hill Dill, and the Indian contact team sport of Kabaddi: Starting with groups of three partners, a selected individual attempts to crawl passed two opposing defenders and touch the wall behind them. Submissions are not allowed, and the crawler can neither stand up nor avoid the defending pair by traversing too far laterally into the play of other groups. Whomever fails to complete their objective during the timed round must perform a set of push-ups before restarting; members then alternate turns as the role of the lone raider trying to reach the wall.
