The TV show's trainers, Shannon Ponton, Michelle Bridges and "The Commando," Steve Willis launched their new series with a huge family workout at Liverpool's Bigge Park. Mrs Bridges was ecstatic by the turnout of participants. "It's exciting to think that we can be inspiring people to want to get out and exercise," she said. Set to make its return on March 17, The Biggest Loser has a new family initiative, The Promise, which encourages people to make a pledge to a family member or loved one to commit to a healthier lifestyle. Mr Willis said he wanted the Australian public to enthusiastically embrace the concept. What The Promise offers is taking it to the next level, taking it to the next step. Having them engage and make a promise to a loved one really ensures that level of commitment, it's an affirmation," he said. Mr Ponton said that becoming a new father emphasised even more that educating the next generation on eating healthy and staying active should be top priority for all parents. "Parents have to start leading by example and be the roles models they always wanted to be," he said. I've got an 8-month-old boy now and from now my promise to him is to always raise him in a fit, happy and healthy household.
