The 46-year-old BBC Radio Ulster presenter, from Carrickfergus, is co-presenting this year's BBC Children in Need in Northern Ireland with Holly Hamilton on BBC One NI. He's married to Natasha and they have two children, Poppy (8) and Robbie (5).
Q: Do you take regular exercise and if so, what?
A: I go to the gym at least three or four times per week, mainly lifting weights (not very heavy weights, but weights nonetheless!) The main reason behind going to the gym was to try and stay in decent physical shape as, being in my 40s now and having two young kids, I didn't want to be running around after them out of breath. I also take my dog for a walk every night but this is more a leisurely stroll than a power walk. Mainly because both my little dog and her owner are getting older.
Q: What is the worst illness you've had?
A: When I was very young (around five or six years old) I had a thing called 'purpura' which is a type of blood disorder. I was bed-bound in hospital for a couple of months, which happened to fall over the summer holidays. You can imagine what that was like for a small boy - absolute torture. I haven't had a day off work sick in 12 years and I am quite proud of that fact.
Q: How healthy is your diet?
A: My diet is pretty good actually. I don't eat much fried food (very rarely actually) and as a family we have a fairly healthy diet. We have a cheat day on Sundays when we usually go and stuff our faces with pizza. I do have a sweet tooth though and have been (fairly successfully I'd say) cutting down on refined sugar. I love anything sweet and especially, having the children, if there is a bag of soft sweets in the house, once they are opened I am the one who ends up eating them. If I am out for dinner I have a healthy main course and then order the sweetest dessert on the menu, usually with chocolate, fudge or salted caramel. I've also been trying to drink two litres of water every day and I enjoy fizzy drinks too, but I'm going for the sugar-free option.
Q: Any bad habits?
A: I drink a lot of coffee and sugar-free drinks.
Q: Do you drink/smoke if so how much?
A: I don't drink alcohol at all. I'm not a fan and even if I was my job wouldn't really allow for it. That, and having two young children who don't seem to be able to grasp the concept of 'lie-in' yet, means alcohol is impossible.
Q: Do you take any supplements?
A: I sometimes take protein shakes if I'm training hard, but bar that, I'm not one for tablets really.
Q: How do you take time out?
A: I love getting outdoors as much as possible, whether I'm with my family or on my own. And the older I get, the more I tend to appreciate the small things like heading to the beach nearby and just taking time to appreciate the wonderful place where we live and frequently reminding myself just how lucky I really am to be able to get outside and enjoy it for a while.
Q: How well do you sleep?
A: I am really lucky as I have absolutely zero problem sleeping. I literally sleep as soon as my head touches the pillow. Literally, head hits the pillow and I am out like a light!
Q: Do you worry about getting old?
A: Not really. I try and embrace getting older, although the odd time I'll catch a glimpse of myself and wonder who that auld fella is. I would worry about aches and pains, as they seem to come round a bit more often these days. These years have been probably the most enjoyable for me and to be honest, I'm fit and healthy and have an amazing family and lifestyle. Maybe if you ask me that in 10 years, when there are some more aches and pains and so on, maybe I'll start worrying more. I am fairly laid-back and don't worry about too much, to be fair.
Q: What is your go-to product that keeps you feeling healthy?
A: It has to be water. And also going to the gym, as my original motivation for going was for my kids, and that remains so. However, I'd say it is an even 50/50 between physical and mental improvement for me when I go. Just spending an hour (sometimes less) there will make me feel physically, emotionally and mentally a million times better than the moment before I stepped inside the gym. It's motivating myself to get there sometimes that's the challenging part. So if I go to the gym and drink a load of water I feel like I'm super healthy. And the older I get the more I buy into 'a healthy body equals a healthy mind' so a lot of my motivation for staying in shape is more mental than physical.
