He said their efforts were encouraging more people to lead a healthier lifestyle and providing an outlet for everyone in Tauranga, especially those who could not afford a gym membership.
"If I can help out in any way I'm more than happy to," he said.
Mr Fa'afili said tomorrow's training would be fun but challenging and would be about starting together and finishing together.
"If it doesn't challenge you it doesn't change you."
He didn't want to put a limit on the number of people who could attend as he could "cater for the numbers".
Miss Pevreal said she and Mr Te Wheoro Lucas, who are using their shared passion for fitness to steer people into healthier lifestyles, were excited about Sunday's session.
She was blown away by Mr Fa'afili's support and said the couple was open to receiving as much support as they could.
Since the Bay of Plenty Times article came out Miss Pevreal said about 15 new faces had attended the training sessions but they had been inundated with Facebook messages from people keen to join in.
To join Sunday's training, message Miss Pevreal and Mr Te Wheoro-Lucas at their Facebook page FIT FAM for LIFE.
