This is our way of expressing our gratitude to the fans of the show.”

He went on to tease that he'd worked with 'many experts to make sure we have even more electrifying and well-designed quests that will leave audiences on the edge of their seats.' he's working with a team to design some new Quests that will put our next batch of uber-fit competitors through their paces.

The new challenges included tough tests of strength, endurance races transporting minecarts laden with heavy sandbags and 150kg rollers, and some an even bigger head-to-head first round.

It was a best-of-three bout; Amotti was defeated in the first round, but powered through to claim the title of Physical: 100 season 2 winner.

He follows Woo Jin-yong, a CrossFit athlete and snowboarder who won the first season.
