The free workout, held on Eden Park's famous playing surface and hosted by former celebrity boxer turned health campaigner Dave Letele, features a world record attempt for the most people simultaneously performing a frog squat. /VCG Photo

Letele, who once weighed over 200 kilograms, is now regarded as living proof that obesity can be overcome and has become an inspiration to thousands of Kiwis. /VCG Photo

While the world record attempt is the fun part, the most important thing of the workout, as written on its official Facebook event page, is for people to "get out there" and "get active," resonating with its ultimate purpose of raising awareness about New Zealand's obesity epidemic. /VCG Photo
