I had always been really active playing team sports but after multiple knee injuries, had to finally admit defeat and hang up my boots. I thought it would be easy to stay really active and go to the gym but keeping motivated on your own was tougher than expected. Id tried other gyms and classes but they never fully stuck. Then I found The Edge and started working with Aideen. I wanted to get back into a routine and invest in myself again and really learn how to build up my fitness and strength in a smart way under the watchful eye of someone who really knows what they’re doing. Ive got all that and then some in my time here. Its been brilliant. I’ve been pushed hard and have learned so much. With having previous injuries, I was nervous starting but Aideen has been great and accommodates sessions as needed while still maintaining the intensity. Going to The Edge is always really good fun and all the trainers make you feel so welcome. Would highly recommend Aideen and The Edge Marino and Im looking forward to getting back as soon as I can.

Aideen’s sessions are always fun and well structured, using a variety of different equipment and exercises. Aideen really takes the time to get to know her clients and knows exactly how to motivate and challenge them. She is always ready to share new ideas and information about nutrition and fitness. It’s a pleasure to train with her!

I joined “The Edge” almost 2 and a half years ago. Had you told me then, that fast forward to now, staying fit had become a staple part of my life, I would have never believed it.

I initially started on my journey with the goal of losing that excess “baby weight” I had put on since having my two boys. What I found at “The Edge” was a community that offered a friendly, positive and safe environment to train and a group of PT’s who were equally as positive and encouraging with a wealth of knowledge and experience to safely guide me through my process. Their support, flexible and commitment to their client base during the current pandemic and lockdown restrictions is further testament to this.

I achieved my initial goal of losing weight but on reflection realise I had achieved a whole lot more. My body is both physically and mentally stronger. Without realising it and with the support of  “The Edge” I had made a lifestyle change that not only helped me find “me” again but helped and continues to help me be the best version of “me” on a daily basis.

My PT James is a mecca of information on nutrition, supplements, sports and body injuries, and of course overall fitness. He will manage expectations so that you are aware of the effort and commitment required to achieve your goals but will push you to achieve your desired goals in a positive and encouraging manner.

Take the time to invest in yourself, it’s the only risk free investment that will return priceless dividends. The Edge and James helped me realise that and I haven’t looked back since.

When I met James his first question was, why are you here. A great question because, it made me focus on what I want, but more importantly he wanted to hear my objectives so as he could apply his knowledge and experience to my situation. My aim is to maximise the return I get from the time I spend exercising, and to ensure the exercise is best for my health and my body. So the ‘ask’ is a personal one, needing a personalised solution.

James’ knowledge on diet and his ability to link diet to a persons exercise regime taking into consideration their own medical history and objectives is invaluable. That to me is his USP, that combination of dietary and exercise advice, is what makes James Swan and The Edge Gym unique in the personal training space.

Since linking up with James and the Edge Gym, I have become fitter, stronger and healthier. My cholesterol has reduced to normal levels through diet and exercise alone, and I now actually get more enjoyment and better return out of exercise than I have ever done over the years.

I started training with Aideen in the hope of increasing my fitness levels and losing weight as I hadn’t been doing much exercise at all and was eating a lot of the wrong foods. I hadn’t enjoyed the gym in the past and Aideen made me feel so welcome and quickly I started to really enjoy and look forward to the personal training sessions with her twice a week. She encouraged me to help me reach my personal goals and checked in on me regularly with helpful tips, recipes etc. Since training with Aideen I lost 10kg and my fitness has hugely improved. I have a much better mindset around nutrition and exercise. I would highly recommend Aideen as a personal trainer.

Absolutely love The Edge gym! Staff are so friendly & professional. Liam has been my coach since last summer for both small group pt & 1:1 training. I find him extremely professional, friendly & approachable and is extremely knowledgeable in his field! Explains every exercise in detail and is a great motivator! Couldn’t ask for a better coach!

Bernie, Marc & Sarah

Myself and my partner Marc decided we’d like to get into shape, but we’d both let our physical fitness decline for so long that we were completely clueless about where to start. We decided to give The Edge a try. From the moment we got in contact with the lovely people in the gym, they were so helpful and put us at ease. There was such a lovely atmosphere there. We felt comfortable and never felt out of place. Then we were introduced to our trainer, Aideen. We were definitely starting at the basics and we were extremely nervous, but she immediately put us at ease. She listened to what we said and worked with us to create a program that suited us. And even though myself and Marc wanted different things, she tailored our workouts to cater for both of us to help us meet our goals. She also took the time to help us get a handle on our nutrition. She sent us lots of recipe ideas and articles on nutrition and health in general. After months of working with our personal trainer and raving about The Edge, my sister decided to join our small group training sessions,  and the three of us started working out together. Aideen was great, and gave her the same level of attention to detail that she had given us.

There is a lovely feeling of camaraderie and fun at The Edge. There is a real sense of team work among the staff. They are so friendly, accepting and flexible there. I really cannot rate our experience highly enough, and especially the care and encouragement we received from our personal trainer Aideen. Thanks for everything guys!

June Meehan

I had never been a gym member before I joined The Edge almost 10 years ago and I have felt a lot healthier since that day. It is always challenging and I feel there is always something new to learn about fitness, strength and nutrition.

It is a gym with a very positive atmosphere.

The Edge is a gym where age and starting ability does not matter, everyone can achieve and develop positive life long habits. That’s been my experience. Training is always under the close supervision of experienced and interested staff. I go to work out but I’ve also got to know so many people which makes the experience even better,  an added bonus!

The Edge is professional and the staff are personable, this is what gives ‘The Edge The Edge’

Catherine Twomey and Louise Ryan

We joined The Edge gym around Oct 2020 and had Mick as our personal trainer. He was great at assessing our individual goals at the start and tailored a program for us which we really enjoyed doing. We could feel the results starting to come, even within a few weeks. When the lockdown hit, we thought we were done for when it came to training, but Mick went above and beyond. He has kept in contact with us weekly to see how we’re getting on and offering his help or advice when needed. He gave us 2 at home workouts to do, based on the equipment we had, to try keep us on track for when the gym re-opens. We’re so grateful for all the effort he’s putting in to help us achieve our goals, both when we were in the gym and during the lockdowns.

David and the team at the Edge did an amazing job in getting me in shape for a World championship sailing event in Dublin. This was the first time I had sailed at that level since I was in my early twenties and the event turned out to be pretty gruelling physically. I was 40 at the time and did not think that training of that type would have much of an effect but the results of the ten week pillars and training program were amazing and made a huge difference to my performance at the event

Joe Kelly

Joe has 2 years experience in the health and fitness industry with a strong interest in Strength and conditioning and Body Physiology. He began at the age of 16 training to help aid his performance on the field. Joe has a background in a multiple of sports but Rugby has been the main focus in the last couple of years.

After numerous injuries he began to look into the causes. He found it fascinating the importance of programming for an athlete as to what the effects of a high impact sport has on the body. This was the start to his career and why he went on to become a personal trainer as his passion is to help people perform not just on the field but in life and live pain free.

Joe continues to up-skill in Body Physiology to ensure his clients receive the best results possible.

I’ve been doing endurance sports, mostly triathlons, for years and started S&C training with James last November with the idea of building up some muscle strength. Little did I know that a year on I would be the healthiest and fittest I’ve ever been and have had one of my best race seasons to date!

Unlike other S&C classes that I had been to, James really focuses on the person and their goals. Each session is very targeted – there isn’t a one plan fits all, rather everything is carefully thought out and tailored to your needs. As important as the strength training, as I’ve come to learn, is the nutrition. I’ve completely changed what and eat and when I eat it and found it has made a huge difference. I’ve never felt stronger and I’ve found that I recover much quicker from hard sessions.

Couldn’t recommend James, or The Edge, more highly for any athlete.

Rebecca Woods

From running, to basketball, to triathlon, James is always up for a challenge! His broad knowledge base, innovative thinking and passion, puts me in the best possible position to progress in my sport. James always wants to be the best he can be, to make you the best you can be. His individualised training not only builds a strong, healthy and knowledgeable athlete, but more importantly, his approach helped me build confidence to believe in my own ability to reach new heights. No matter your sport, athletic ability or skill level, James has the knowledge, drive and experience to help you achieve your goals. His energy and enthusiasm is contagious! James has helped me to become faster, stronger and more effective in my sport – he has given me ‘the edge’ I need to succeed!

I began training with Chris in April 2018, while I had lost some weight I was stuck in a rut and needed something to change. I was so nervous going to the gym the first time, but that was eased once I had a chat with Chris. He asked me what my goals were, this wasn’t just about going to the gym but a lifestyle overhaul and I was ready to embrace this change.

I started with one PT session a week and was in pain for days after it, but that was a good thing, I could feel the change happening. Chris’s support was immense and I don’t think he fully understood how much the texts he sent mean to me. Just that reassurance that I was doing well.

After some persuasion I did a class in The Edge ( I didn’t think I would be able to keep up). This was a new concept for me, it was pushing my comfort levels out. But all the time knew Chris wouldn’t have suggested it if he didn’t think I was capable.

Over the past 7 months the change has been amazing. I’m reaching my targets and setting new ones too. Chris is always only a text away for any of my queries. I am so grateful for this and I think he underestimates how much this constant support has helped me during this time.

Estimating calories burned during your workout

Are you overestimating the amount of calories you are burning during your workout?

According to a study conducted in Stanford University on calorie and exrcsie counting devices, Apple, Samsung and fitbit included, the step counters where accurate but the calorie counting ability has been completely overestimated. The researchers concluded that a 5% difference would be acceptable but a 27-96% had been observed between samples.

Calculating calories burned during exercise can be a tricky game, as many variables are needed to control for accuracy, including height/ weight/ current fitness levels/ diet/ intensity of exercise/ sex etc…

The obvious issues that many trainers/ trainees are seeing is alterations in daily calories in response to the “inaccurate” data received from the calorie counting device, which obviously leads to issues with motivation, results and measurements.

To combat this its important to note that unless you are enduring long bouts 1 ½ – 3hour training sessions for example long distance running/triathlon or Crossfit then according to a recent publication by the Mayo clinic, your weight loss goals should be controlled by diet “reducing calories is a much better predictor of weight loss than exercise alone”.

Like always it’s best to talk to an exercise and nutritional professional and leave the frustration and guesswork aside.

Elaine Gallagher

I initially began training at The Edge to lose some weight for my wedding.  Starting off I joined the X-fit programme, attending semi-private sessions twice a week and occasionally trained at the weekend.  I found X-fit perfect for getting me started, with the team helping to set achievable goals for the 10 weeks and educating me on nutrition as well as offering healthy lifestyle tips.

As my wedding day loomed I decided to start personal training alongside of X-fit.  As soon as I added PT with Harry to my weekly training I noticed a difference.  I was getting stronger week on week as well as losing weight. Harry is a great trainer, always pushing me and making each session more challenging, but I loved it (just not all the burpees).

I suffer with lower back problems but this didn’t impact my training, Harry would tailor my sessions whenever I was having problems.  And now, thanks to my training I have noticed huge improvements in my core strength and in my ability to complete more sit ups / core exercises, as well as lifting progressively heavier weights & generally push myself harder throughout each session. I find I actually look forward to my workouts.

Harry has an obvious passion for fitness and health and thanks to him I shed 5kg and 4% body fat in the run up to my wedding and I couldn’t have felt better on the day.  I would 100% Harry and The Edge for anyone looking to start lose weight or improve their fitness.


After many attempts at losing weight, I was lucky to find a gym-next-door: The Edge. I started training with Aaron in the morning X-Fit program. When I joined, my ultimate goal was to hit 102 kg within 12 months. Thanks to his tailored guidance and tips on both exercise and nutrition I was able to go down from 116 to 107kg and lose 6% body fat in less than 4 months. Aaron was great at finding ways to motivate me with challenges both in-class and out of class. But most importantly, training became a lot of fun, and now it’s part of my routine.

In May 2017 with great encouragement from Chris I started at The Edge Gym and opted to join the classes, participating in 3 classes a week at 6.15 am. I thought I would initially join for a month to give me a boost for my summer holiday and quickly found myself hooked. I was made feel very welcome and encouraged by Aaron,Harry and Sean Paul. After a couple of weeks I could really notice a difference, I was eating and sleeping much better, the inches and weight started dropping so I kept going and now here I am 5 months later and I have shed 13kgs and 5% body fat.  A huge thank you to all at The Edge team for the consistent encouragement and patience, they are a fantastic group and the range of classes are great, suitable for all ages and they change them up every couple of weeks so your always being challenged. Chris gives me great nutritional tips and I now eat 6 times a day rather than 3 never letting myself get hungry. Role on Christmas and that little black dress.

Stephen O’Brien

Just over 12 weeks ago, I did a 5km fun run with work which turned out to be a real eye-opener for me and where my level of fitness was at. As more and more people were passing me out it really hit me that I was in a bad way! So that weekend I built up the courage and contacted The Edge for help.

After my first consultation with Harry, he identified where I was going wrong; not sleeping enough, not eating at the right times and not training properly. Having assessed me, Harry then made up a plan and I haven’t looked back since!!

I’ve been training with Harry in The Edge for just over 10 weeks now and have gone from over 103kgs down to 90kgs ! This has been down to a detailed diet and training plan which has been set out for me. The sessions have been tough, Harry never let me get comfortable – changing my programme every few weeks so I didn’t get bored. Harry has been very supportive but also strict when he needed to be… one day I hope to smash up that airbike!!

I would 100% recommend Harry or any other trainer in The Edge. There is a great atmosphere down there and it’s a brilliant environment for people to achieve their fitness goals.

Una Lowry

I decided to get some personal training sessions when I got sick of nothing fitting me any more. Initially it was just for a few weeks to give me a kick start, 6 months later I have no intention of stopping.

Since I stared with Harry I have lost roughly 15kgs without feeling like I’ve missed out on anything. I was terrified before my first session between being so out of shape and the fear of the unknown, within minutes Harry had me at ease even though it was tough.

He regularly changes my workout plans to stop me getting bored, and knows when to go easy on me and when to push me harder, especially when I’m losing motivation or close to reaching a goal.

He’s also great to bounce recipe ideas off so I don’t end up eating the same thing all the time. I’m not where I want to be yet but I know with Harry’s help I’ll get there. I’m very lucky to have him as a trainer and a friend. I would recommend him 100% .


I’ve been training with Chris for some time now and am really happy with the results. Via a diet and workout plan, I have made some real progress in my squat, deadlift and bench with a well-constructed plan focused on incremental increases- the result being I am stronger than I have ever been, with for example my squat moving from 100kg to 140kg over the past 2 months alone. Supporting this is a focus on diet and getting the right combination of foods and nutrients. I travel a lot with my work and Chris has gone that extra mile by frequently sending programs that I can do at my hotel so that I don’t fall behind my goal. My energy levels are great and I enjoy working with Chris- good laughs and thanks for all the progress so far!


Sean Paul Power

It is so important to keep training between events. If I do stop, it can easily lead to becoming rusty and losing the conditioning needed to compete in my preferred sport. The training itself does not have to be as intense as in competition training as this could lead to burn out, but instead focusing moreso on improving technique and staying ‘ready’. Training with the Edge lads gets me back to competition training so much quicker than before, and I am in the best shape of my life!


Danielle Nolan

I’ve been training with Chris for seven months now and it’s by far the best investment I’ve made. He took the time to understand my goals and tailor each programme towards them. He consistently changed up the programme and monitored body measurements to keep me interested and motivated. Outside of our gym sessions Chris took the time to analyse my food and shared plans to help keep me on track. Chris’s impressive knowledge of weight training, diet and his friendly manner makes him a joy to train with I would highly recommend him as a trainer.


Ashling Branagan

ash-bran-largeI had been working out in the Edge with my personal trainer Sean for nearly a year before I found out I was expecting. I typically did 2 personal training sessions a week as well as 2/3 group classes per week. The gym has always been an outlet, I find it so good for my mood and overall wellbeing. I was really scared telling Sean I was pregnant, I was so unsure about training when pregnant and thought I would have to give up the gym (I obviously had no clue!). I told Sean pretty early on, he was so supportive and really informative. He explained I could do exactly what I had been doing but that he would make adjustments as the weeks and months progressed. He stressed to me about listening to my body and taking things slowly.

Once I met with Sean I felt great, I was really relieved and happy with his support and knowing I could continue my training.
I am really competitive with myself when it comes to the gym and quickly realised that my ability to lift weights and train was just not the same. I battled for the first few weeks trying to keep up with the old pre-pregnancy me but I just couldn’t. I was so frustrated with myself and expressed my concerns to Sean. He kept telling me to take it easy, not to be hard on myself and to listen to my body. So I changed my mind frame, began listening to my body and doing what felt comfortable for me at that time. I quickly got into the swing of things (my new normal!).

Sean altered my program every couple of weeks depending how far along in my pregnancy I was as different trimesters needed different alterations to my training. Sean was so informative about exercises that were particularly good for pregnancy and always checked in with me about my eating and how I was feeling. I found that when I listened to my body I was more than capable of doing a lot of the same exercises that I did pre-pregnancy.
As well as my PT I kept up classes and found all the trainers were great at altering exercises for my needs. They would always check on me and ask how I was doing during classes. Over the 9 months nothing really changed for me regarding the gym, I still trained 3/4 times a week until the end of my pregnancy. I found training so helpful, I had a lot of strength in my lower back and core, as my belly grew which helped me avoid any back pain. I also found training helped with my sleeping as I slept so well throughout (don’t hate me for that!). I trained up to 38 weeks pregnant, and made a decision with Sean to go for walks and keep up pelvic floor exercises for the last two weeks until the baby was due.

I didn’t fully realise the impact that training had on my body whilst pregnant as my belly was growing by the weeks. But now a few months postpartum I feel my recovery has been amazing because of my training. I have started back at the gym and yes it has been tough getting back into it after a few months off but even after a couple of weeks I feel my strength and fitness is coming back really quickly. Sean and the team at the Edge are great and really informative about training when pregnant as well as post pregnancy training!


At the age of 14 years old I was told I had to have an operation to correct a 60% scoliosis curve in my back, called spinal fusion. Post operation, it had only been corrected to slightly above 80% along with 2 metal rods permanently placed either side of my spine from my neck to the base.
Up until the age of 19 post operation I never did any physical training or resistance training. Prior to starting to train I would consistently have back aches and pain…

I’ve been training at The Edge with Andy for 6 months now and these problems have totally gone- I feel like my back is stronger then ever along with seeing a massive physical difference and being more confident in how I look.
I’m just so delighted with my results and feel like I’m getting stronger and stronger all the time- the guys have been fantastic and I really cannot recommend them enough. It’s not all about six-packs and getting big and so on…

These guys are genuinely fantastic and I cannot thank them enough.
