Since you’re reading this, you’re probably an ambitious athlete who wants to:

  • Develop a performance-enhancing physique

  • Improve your recovery and durability

  • Fuel to perform at your best

If that sounds like you, you’ll probably resonate with many of the athletes I’ve worked with…

GAA player Ronan O'Neill Nutrition gaelic football Nutritionist

“I always hoped I’d get to where I am today condition-wise, but didn’t think I could. Now I am, and know I can get even better still! Loving how I've managed to get everything under control. Happier with my body. Just loving the spot I'm in physically and mentally. Again, thanks a million for it all.” - Ronan O’Neill, GAA Athlete

“I feel like I've gotten more pace and I'm moving better than I have in the last few years. I always would have taken these things seriously, but really leaning into it and dialing in with yourself has made a massive difference for me!” - Paddy Burns, GAA Athlete

“I always felt I had a fairly good knowledge when it came to nutrition but you've brought me to the next level.” - Alan Cox, Hurling Athlete

For you, this might look like:

✅ Learning how to eat to fuel your body so that you go into training sessions confident that you’ll have high, sustained energy levels throughout.

✅ Dropping the extra kilos of body fat, so that when you look in the mirror, you see an athlete looking back, and your body composition is optimal for your performance goals.

✅ Implementing performance-enhancing nutritional strategies around competitive events like matches or races, so that you're able to simply go out and express yourself on the big day.

✅ Setting up your nutrition to support general health and recovery so that you're showing up to training (and life outside of it) with energy and vitality.

Reducing injury risk, so that you can train and compete all year, knowing your body is durable enough to withstand the hard training.

✅ Building sustainable habits that will carry you through not just the coming months, but also your entire sporting career and beyond.

Or, if you're like most of the athletes I work with, a combination of all the above.

If that sounds like you, you’re in the right place…

“Thanks a million for all of your help. Feeling unbelievable and looking forward to seeing how it shows on the pitch! Delighted to have gotten well under the 20 minute mark the 5k run, feelings extremely fit compared to where I was this time 12 weeks ago. Showing improvement across max push ups, pull ups, and burpees that I can do too, so winning all round.” - Cathal, GAA Athlete

“Just want to say thanks very much for the past six months. Couldn’t have imagined the changes from then to now and really feel this is a new starting point all over again to make more progress. I feel stronger faster more mobile and powerful and an awful lot leaner. I did the inbody scan yesterday and the changes from the first one were crazy. 7kg decrease in fat and up 1.5kg in muscle. The accountability was great and now at this stage it’s purely habit and enjoyment that I train for. “ - Niall, GAA Athlete

GAA player Aaron Kernan Nutrition gaelic football Nutritionist

“We put a plan in place early in the year and set targets for weight etc. all of which I met. I was taking part in every pitch session throughout the year and lasting the full 60 minutes, still hitting speeds and distances throughout games like I would have always done. At my age, this wouldn’t have been possible without your advice and guidance.” - Aaron Kernan, GAA Athlete

Allow me to introduce myself…

My name is Conor O’Neill and I’ve helped 1000+ athletes train harder for longer, improve recovery and durability, and develop a lean, athletic physique.

As an athlete myself, I played Gaelic football since childhood, right up to being part of an All-Ireland Club Championship winning team with my home club Crossmaglen rangers.

Since finishing football, I’ve dabbled in Olympic lifting, strength training, and physique change, but now, my main sport is endurance running, where I’m currently working towards a sub-3-hour marathon.

As much as possible, I aim to put myself in the shoes of the athletes I work with, putting “skin in the game” by pushing myself to pursue my own ambitious athletic goals.

I then combine that experience with my education in nutrition, psychology, and performance to help them fuel to perform at their best.

Performance Nutrition Coaching

Here’s what’s involved…

1. Your Initial Assessment Call

We start by getting a clear picture of you as an athlete right now: your goals, training demands, lifestyle, and current nutrition approach.

We'll cover your nutrition history, physical metrics, key challenges, and what's driving you, so your plan is fully tailored to you from day one.

2. Your Performance Nutrition Plan

We'll build your clear individual strategy, designed around your sport, training, and real-world commitments.

This could include:
Calorie and macronutrient targets based on your fuelling and body composition needs,
Meal timing and fuelling strategies around training and competition,
Practical meal structures to give you full clarity executing the above,
Clear and actionable hydration, recovery, and supplementation strategies,
And other performance strategies you may need based on your goals.

Training programming (full S&C/running plans or specific elements) can also be included where needed.

3. Your Weekly Review & 1-to-1 Support

Each week, you’ll take a few minutes to review your past week, allowing us to make and adjustments to the plan, get across any resources you might need, and address any sticking points you might have.

You’ll also have direct access to my WhatsApp with any questions you have in between those weekly check-ins so that you're never left guessing and are clear on how to handle the unique and changing demands of each week.

4. Your Monthly Momentum Call

Each month, we grab a 1-to-1 call to zoom out and review everything in more depth.

On this call, we have an open discussion around what’s been working for you and what you’ve been struggling with.

This allows us to go deep, sound-board, discuss any issues in real time, remove any guess-work, and plan out your next steps.

5. Continuous Development & Life Integration

This isn't a one-off plan.

As your training, season, and life evolve, your nutrition system evolves with it.

The goal isn't simply to help you make short-term progress.

It’s to build a performance nutrition system that works now, and can also be integrated into your life for the long-term so that you make progress, sustain it, and continue to improve long after we’ve finished working together.

“Just want to say a massive thanks for the last few months, really enjoyed getting my body to the best shape it's ever been in and you kept it nice and simple.
