About

Hi, Im Brian Flaherty, I founded Performance Dynamics out of a love for sports and exercise science, and a desire to make it available to all.

After completing a degree in sports science and a masters in strength and conditioning, I found myself working with athletes and individuals who wanted exceptional results.

I quickly learned that when things are overcomplicated, they don’t work. When you apply the same logic to everyone, they don’t progress. When you don’t measure your desired outcomes, they don’t happen.

What does work, is accurately measuring what you want to improve, simplifying that information to make it actionable, and applying it to the individual at their appropriate level.

I set about creating systems and structures that make this process simple, and Performance Dynamics was born.

    The online programme is so easy to follow, well-structured and demonstrated, and its progressive. Online training really suits me as it provides flexibility around when I train.

I’ve been working with Brian Flaherty since his playing career was cut short due to injury. He seamlessly transitioned from player to coach and has proven to be an integral part of our Management team. Through his regular testing we get a constant metric of where we are as a group it also gives us a point of reference so we can monitor changes both collectively and individually.

He also has an innate ability to motivate players and drive standards which has helped create a far better environment and team culture.

I would highly recommend Brian and I wish him well in the future.

A key focus for us is to develop our young athletes to their fullest potential. Performance Dynamics enable us to track long-term athletic development with their high-quality testing and data outputs. This allows us to see how our training systems are working, and direct future training appropriately. Sports science has become such a big part of modern sports, it’s great to be able to utilise it in our rugby program.

Very professional service that provides easy to understand information.

I started my online training with Performance Dynamics about nine months ago. I had some old injuries which affected my mobility and gave me pain and discomfort day to day. I also had radiating nerve pain from my neck down my arm from a car accident a few years before. I joined a gym and worked hard and consistently but I was still in pain. The more I tried, the worse it got.

I realised I needed professional help. After a consultation, Brian delivered a training plan to address my issues which included improving mobility, building strength and stability, and reducing my body fat percentage. I quite quickly learned that strength and mobility training could address all my issues and could also improve my bone density. I am a 52-year-old female, so this is important to me. I also learned that my everyday life was contributing to my pain, not just the car accident. This is probably the most important thing that I learned. Once I understood this, I realised that patience and perseverance would yield results.

The online programme is so easy to follow, well-structured and demonstrated, and its progressive. Online training really suits me as it provides flexibility around when I train.

I have significantly reduced my pain and discomfort, I move better, I stand better, and I even breath better. I have managed to decrease my body fat, I feel so much stronger and surprisingly, the shooting nerve pain is completely gone. I look forward to continuing this journey as I know the results are very real. I highly recommend Performance Dynamics online training to people of any age, they are professional, knowledgeable, and so easy to work with.

I came to Performance Dynamics a couple of years ago after I had been trying to get a personal trainer for months. I have an acquired spinal injury which paralysed my left leg, and I was in a wheelchair, so I got turned down by a lot of people.

Then I met Brian from Performance Dynamics, and things started to change.

After a consultation he agreed to take me on, and we hit it off straight away. I was really enjoying the training, I was losing weight and getting stronger and then one day, I started to get sensation in my left leg. A mild tingling to start but I knew something was happening.

Within 2 months I was out of the wheelchair and walking short distances, within 6 months I was not using the wheelchair at all. Since then my life has totally transformed, I got engaged to an amazing man and have moved to a beautiful part of Tipperary. I graduated to online training with Performance Dynamics and have made a lifelong friend in Brian.

I could not recommend Performance Dynamics enough, they helped me to transform my life. With a positive attitude and a desire to make things happen, anything is possible.

I have been with Performance Dynamics for just over a year now and I can honestly say it was the best decision I have made regarding my health and fitness!

The results I have achieved to date are due to the perfect combination of resistance training and mobility methods. I have reached goals and hit PB’s I never thought were possible before this. The professionalism, extensive knowledge and dedication from Performance Dynamics provides the perfect environment for everyone to progress and reach their own specific goals.

I would recommend Performance Dynamics to everyone. They will help you find the strongest, healthiest version of you.

I have been training with Performance Dynamics for two months now in the small groups. I was going to a gym on my own, but I just wasn’t making progress, had no idea if I was doing things right.

I’ve learned loads so far, I feel much better and I’m confident now that I’m doing things right. Looking forward to the next couple of months, cannot wait to see how much progress I can make.

I started training with Performance Dynamics around two years ago. I was training in a pair with my friend, it was so much fun. Both of us had injuries so we thought Brian was the right person to help us because he has so much experience in sports. Within a few weeks we were flying it, we were training well, we both dropped dress sizes and the injuries were not getting in the way at all.

I took a break for a little while and I was dreading getting back into it. When I came back, I went into a small group because I had some experience already. I’m so glad I did because its such a great atmosphere train in, and I’ve made even more progress than the first time. I’m stronger now than I have ever been and I’m dropping more sizes.

It had been a few years since I had been in a gym or playing sports at a competitive level. I have been going to Performance Dynamics for nearly 3 months now doing their small group coaching three times a week. I have seen huge improvements in myself, from feeling more energetic, my clothes fitting better, moving better, and lifting more.

The effort that goes into planning my program and guidance for my diet is fantastic.

Within the sessions they do a great job of monitoring, and quickly adapting to play to my strengths and improve my weaknesses.

I have highly recommended Performance Dynamics to my friends and family.
