The Happy Pear brothers have revealed how they deal with social media and criticism from people online.
David and Stephen Flynn are the twins behind the hugely successful health and wellbeing business.
The pair recently launched their Healthy Living podcast series, with the first episode featuring fitness guru Joe Wicks.
Their upcoming show will star Russell Brand whom they describe as a "great guy" and friend.
Speaking on Alive and Kicking with Clare McKenna, the brothers explained how they cope with negative comments online.
"We totally realise we're Marmite, we're definitely not everyone's cup of tea," they said.
"We're some people's kombucha, but we're not everyone's cuppa Barry's tea.
"Certainly ten years ago, if people were giving us criticism or saying something on social media, it would have hurt us much more, whereas now, you're kind of used to it, and maybe it is a coming of age thing.
"You kind of know it's not personal, someone might be feeling bad, and sometimes it might be personal, but you can't please everyone."
They added: "I always liked the expression, 'to lead an orchestra you have to turn your back on the audience'.
"I always think that's a great reminder for us to keep doing our dance, some people will love it and some people will hate it, and that's alright."
As long as they are still close with their family and friends, the Happy Pear twins are happy.
However, they conceded that it can be a struggle to deal with social media some days, and they try to manage their relationship with online platforms so they "don't get dragged into the weeds or into the gutter of it".
