About One Arena

About One Arena

One Arena was set up in 2016 by Edward Finn. Looking to give more to his clients than just results from their training and diet, He wanted to create an environment and atmosphere where people would thrive. Guided by highly motivated and passionate people we want to provide a facility full of energy, enthusiasm, and achievement.

We focus on health and structural balance first. This is an integral part of our culture. People are our passion and our personal service will be the backbone of the business. Fitness to One Arena is being able to live a healthy well-balanced life. It is more than just a physical capacity. Fitness has intellectual, emotional and social concepts. As personal trainers, we aim to educate, inspire and empower through physical fitness.

Frequently Asked Questions

Your journey starts with a full assessment which includes a body composition testing, movement compensation screen, a mobility, strength and structural balance test, along with a nutritional analysis to maximize your potential.

From here we go to the gym where we run mobility, strength and structural balance test, a plan is then devised based on your results. We will add a degree of variation which involves making adjustments in the training programme to provide new stresses to the body, which will overload the body and thus cause it to adapt. After your programme is finished we retest and go from there.

We train our client’s specific to their goals. When we meet a client for the 1st time we go through a detailed assessment of them. Each client is progressed according to their level of training experience. We work with total beginners, Olympic athletes and everywhere in between.

Book in for your complimentary assessment where we can discuss your goals in more detail and devise a plan for you.

I am a qualified personal trainer with a MSc in business and marketing. My fitness journey started at a young age.

Hey guys. My name is Sinéad McElligott! I have just qualified as a personal trainer and I have been lucky enough to have the opportunity of joining the team in One Arena.

Fitness has always been a passion of mine. I have first-hand seen the benefits of exercise both physically and mentally, and I decided I wanted to educate people so they too could see these benefits.

On the side, I’m a registered general nurse and have always had a love for health and caring for people. I am there for the clients to help them both physically and emotionally, to help them to progress, just like I am with my patients. Building relationships with the members is key for me in order to make them feel comfortable and safe.

I try to make the sessions as fun as possible while also encouraging members to challenge themselves (even if it does include a few extra burpees). I’m very excited about working in One Arena and can’t wait to meet you all.
