While Bec found fame on the long-running Australian soap Home And Away, the couple have leveraged their high profile for the purpose of promoting healthy food.

In the latest project, the couple participated in a rather cringe-worthy web series entitled Bec's Boot Camp for Hans Continental Smallgoods. 

In one particularly cringe-worthy video, Bec's alter-ego character unleashes an aggressive elderly Greek woman upon Lleyton in the hopes that she will teach him how to extract oil from olives using traditional methods.
