The exercise guru is expecting her first baby with Paul Byrne next May and the pair are over the moon about their good news.
The mum-to-be completed an Ironman challenge while pregnant last September and took it all in her athletic stride.
She teamed up with celebrity clients Rosanna Davison and Kathryn Thomas for the gruelling relay challenge, going on to win the women's event.
"I suspected I may have been pregnant, but I was only about three weeks gone at the time and I didn't notice any difference in terms of my performance. It's funny thinking that the baby has already done an Ironman challenge," she said.
She and her husband have spent years in their city centre gym helping some of our best-known personalities stay in tip-top condition, including Grainne Seoige, Keith Duffy and Brian Kennedy.
And as far as she's concerned, it's business as usual, despite being 15 weeks pregnant.
"We both start work around 8am and do about eight hours working in the gym with clients. There's nothing that I don't do now that I wouldn't have done before; I'm just more careful with myself and I make sure not to get my heart rate too high.
"I have done an Ironman and my body is used to doing all sorts of exercises. I have slightly modified my routine but my golden rule is, if I'm not comfortable with something, I won't do it.
"In a few months, I'm going to be really using my abs, so I don't want them to be too soft, so I still do a lot of heavy weight training, swimming and cycling."
She's also lucky in that she has been craving "lots of clean food" like fresh fruit and vegetables, and has completely eliminated all junk food from her diet.
"I've trained a lot of pregnant women in the past and I fully believe that, if you give your body healthy food, that's what it will crave.
"I'm very lucky in that I've a brilliant husband who has kept a very close eye on me and will nudge me in the right direction."
