Australian cruisers have a chance to get in shape with Biggest Loser trainer and Carnival’s new fitness ambassador, Shannan Ponton when he joins two Carnival Spirit sailings this year.

The line recruited the fitness expert in February this year to provide Spirit and Legend guests with healthy alternatives.

He has since worked with the line’s chef to create nutritious food onboard including a turkey burger on a chia and quinoa bun as well as provided samples of his trademark workouts in the gym.

He also hosted the Biggest Bootcamp at Sea last month, with over 500 guests joining him on the top deck of Carnival Spirit for a workout session.

But now cruisers will be able to workout with the man himself, when he joins two Pacific Islands cruises departing 23 July and 12 August 2014.

Shannan said he was keen to get back onboard.

“I’m going to hit the gym first thing for a spin class, or a circuit, then maybe an abs class,” he said.

“Then I’ll relax on deck with a cold drink, and of course play some mini golf with my son too.”

Prices for the nine-night cruise departing 23 July start from $979 per person twin share and the eight-night cruise to New Caledonia departing Sydney on 12 August 2014 is priced from $909 per person twin share.
