When you’re a former reality TV star with a chiselled body that would make an Olympic swimmer envious and a social following that amasses over 100k, you might be tempted lift your foot off the gas. Life is good, after all. But for personal trainer Lonan O’Herlihy, it’s all hard work, all the damn time.

“24/7, my life is based around my work – I never rest. It sounds intense, but I am an extremist. I know exactly what I need to do to get me there,” explains O’Herlihy.

O’Herlihy wasn’t always health-obsessed, but he loved sports as a youth. Growing up, he was tall and very lean at 6’3” and 150 pounds, and sustained numerous injuries from soccer and rowing. Rehabilitation at the gym revealed how his body could change to become bigger, faster and stronger.

This Brit doesn’t just preach a healthy lifestyle though – he truly lives it. When he releases a 30-day nutrition plan to his scores of followers, he follows it too. When he posts a 15-minute bodyweight workout, he’s tested its effectiveness. When he has a cheat day, he documents his indulgences during a night out with girlfriend Millie Lindsay.

For O’Herlihy, the number one excuse for not getting off the couch and changing your lifestyle is lack of knowledge. His key to success is to educate, motivate and give several reality checks to his clients. There’s no skipping leg day with this guy. But don’t think that his self-discipline allows for zero fun. The personal trainer has a cheeky British wit and self-deprecating sarcasm, softening his powerful Adonis-like demeanour. “I have the waist of a 14-year-old girl! Nothing fits me,” O’Herlihy laughs.

We spent time with the celebrity trainer in his Chelsea neighbourhood to see how he kicks ass from day to night, and discovered what it really takes to maintain a healthy lifestyle.
