Whether you want to lift heavier, run faster, race harder or simply feel better day to day, we give you the tools, coaching and structure to reach your full potential.
I’m Dennis, an injury rehab and performance coach empowering driven, ambitious athletes to unlock higher levels of fitness, resilience, and a true competitive edge.
My journey through training, competition, and coaching across multiple disciplines has shown me what truly drives long-term progress. It’s not extreme workouts or quick fixes. It’s consistency, smart structure, and an understanding of how the body actually adapts over time.
Over the years, I’ve seen too many athletes held back by poor programming, rushed progressions, or training that didn’t respect their body. That experience is what pushed me to build a coaching approach focused on sustainability, performance, and long-term development, not burnout.
At Conroy Performance, I combine evidence-based training, structured programming, and a strong emphasis on recovery to help athletes move better, perform stronger, and stay in the game longer. Every plan is built around you, your goals, your lifestyle, and your current ability, not a one-size-fits-all template.
Whether your goal is to return from injury, improve performance, or simply feel stronger and more capable in your body, my role is to give you clarity, direction, and the confidence to execute your training with purpose.
No fluff. No guesswork. Just intentional coaching built for real progress.
If you’re ready to train with clarity, push your limits, and build performance that lasts, I’m here to guide you every step of the way.

Posted on Google Fi ForTrustindex verifies that the original source of the review is Google. Dennis has been fantastic training my daughter while she rehabs from shoulder surgery. She loves the sessions and he gives her support and structure to her training between sessions too.Posted on Google Henry BudgeTrustindex verifies that the original source of the review is Google. Conroy Performance was a total game changer in preparing me for my Hyrox event. Dennis coached me through a structured 12-week Hyrox programme, complemented by in-person sessions leading up to race day. His coaching was high quality, motivating, well designed, and tailored to help me perform at my best. The programme was delivered via the Fitr app, which made it easy to follow. Each session was clearly laid out, with detailed programming that made tracking progress simple and kept me consistent and accountable throughout the 12 weeks. What really stood out was the ongoing support Dennis provided. Whether it was fine-tuning technique, staying on track, or answering questions, he was always responsive and genuinely invested in my success. I’d highly recommend Dennis and Conroy Performance to anyone serious about levelling up their fitness or getting race ready. Whether you're training for Hyrox or just aiming to boost overall performance, you're in excellent hands.Posted on Google Sean McGrathTrustindex verifies that the original source of the review is Google. Immediately after getting a ticket for my first Hyrox, I contacted Dennis regarding his 12 week Hyrox programme as I wanted a specific plan geared towards the event. We decided to also incorporate some 1 on 1 sessions alongside the programme. These were excellent at addressing some technique concerns I had with certain stations, running pace, nutrition advice and also incorporating extra exercises around a shoulder injury I was carrying. I felt very well prepared at the end of the 12 week programme and thoroughly enjoyed my first Hyrox. I am already eying up a half marathon and perhaps another Hyrox by the end of the year. I would 100% recommend Dennis as a coach not just for Hyrox but anything strength and conditioning related. He is very reassuring, proactive, informative and shows a genuine interest in getting the best out of you. I had some nerves beforehand and he very much put me at ease and assured me that I was ready and had put the necessary work in.Posted on Google Adam LucukTrustindex verifies that the original source of the review is Google. Dennis is a knowledgeable and proactive personal trainer. He looks to tailor training and rehabilitation programmes around the client's needs and requirements. He recognised my Hip condition as FAI (Femoroacetabular impingement) ahead of medical diagnosis. He created a programme to help me manage the condition, allowing me to avoid a potential medical procedure.Posted on Google K LTrustindex verifies that the original source of the review is Google. My daughter has been training with Dennis at Conroy Performance following shoulder surgery, and I cannot recommend him highly enough! From the first session, it was clear that he is highly knowledgeable, professional, and genuinely invested in her recovery. Dennis has helped her regain and improve strength and mobility and boosted her confidence throughout the process, which has been reassuring for both of us. Beyond the technical expertise, what sets Conroy Performance apart is the supportive and encouraging environment they create. Rehab can be tough, but Dennis' positive energy and motivation have made all the difference.Posted on Google Penny LoweTrustindex verifies that the original source of the review is Google. I reached out to Dennis for help in creating a more structured training plan, as I’d been dealing with injuries that were limiting my progress. I wasn’t sure how to move forward, but Dennis provided the guidance I needed. During the initial consultation, we set the groundwork for my bespoke rehab online coaching. Three months later I’m trusting the process and I’m on my way to being injury free. My training now has clear structure, pushes me out of my comfort zone without being overwhelming, and most importantly I’m having fun again! I check in with Dennis on a weekly basis, which ensures everything stays on track, and he’s always available to answer any questions I have. Thank you Dennis (Conroy Performance)! I highly recommend his training.Posted on Google Robert GurneyTrustindex verifies that the original source of the review is Google. Dennis and Conroy Performance has been nothing short of amazing. He’s pushed me to the next level of my CrossFit and really helped my confidence grow in the 3 months I’ve been training with him. Dennis’s online coaching really is bespoke as he listens to all the feedback I give and changes my plan accordingly. An example of this is when I injured my shoulder early in the program and he changed it to help rehab my shoulders whilst still improving and training as much as I could. I would recommend Dennis to anyone who wants to improve their CrossFit and take their training to the next level! I’m very excited to continue working with Dennis and looking forward to compete next year!Posted on Google Jennifer TeacheyTrustindex verifies that the original source of the review is Google. I highly recommend you consult Dennis if you have specific training goals as his expert guidance will help you successfully and healthily achieve them. Dennis is a very skilled and knowledgeable personal trainer. He is adept at creating workouts specific to the individual and their goals. He helped me improve my running form to prevent injury as well as identify and avoid an injury reoccurrence. My overall strength has improved, and I’m well placed to begin setting some more personal bests thanks to Dennis’ help and expertise.Posted on Google Jessica RosethornTrustindex verifies that the original source of the review is Google. Dennis is an incredible coach. He has been essential in my rehab journey recovering from a herniated disk - very clear in what I should and should not do, motivating, clear and also just a great sounding board for dealing with the mental side of it all. Overall just a really exciting rebuild. Would recommend in a heart beat!Posted on Google Hannah ColeTrustindex verifies that the original source of the review is Google. I’ve been training with Dennis for the past seven months, aiming to improve my strength and specific CrossFit skills. I also sought a tailored plan to push me out of my comfort zone and support my participation in various events throughout the year. Thanks to his dedication and hard work, I’ve successfully competed in events such as the London Hyrox, a half marathon, and the Summer Turf Games. Dennis is highly professional and communicates clearly, making it easy to understand and meet my needs. I would highly recommend him if you’re looking for a top-tier coach.
You want clear, honest answers before you commit your time and effort to a coaching programme. This FAQ page is designed to give you a straightforward overview of how coaching with Conroy Performance works, what you can expect, and how we support you in your training.
From in-person sessions to online coaching, you will find answers to the most common questions about our services, approach, and practical details so you can decide whether we are a good fit for your goals.
We offer in-person personal training, in-person performance testing, and online coaching. All coaching is built around your goals, your current abilities, and the time and resources you have available.
Coaching is aimed at driven and ambitious athletes and committed trainees who want structured, evidence-based training to improve strength, conditioning, performance, and resilience. You do not need to be an elite athlete, but you should be ready to train consistently and take your progress seriously.
In-person coaching gives you hands-on coaching, live feedback on your technique, and performance testing in a fully equipped gym based in Harpenden (St Albans).
Online coaching gives you individually designed training that you complete in your own gym or training space, supported by regular check-ins and feedback. Both follow the same principles, with the format adjusted to what works best for you. Clients can choose to combine in-person sessions with online programmes for best results.
All coaching programmes begin with an initial conversation about your performance goals, injury history, training background, schedule, and access to equipment. This helps us understand what you need and whether we are the right fit. From there, we outline the most suitable coaching option and the next steps.
The first phase focuses on assessment and clarity. We establish your starting point, set clear goals, and design a plan that matches your current level, rather than forcing you into a generic template. For in-person clients, this can include performance testing. For online clients, we work with the information you provide on your abilities and training environment.
Programmes are designed to be realistic and sustainable. If your schedule, training load, or circumstances change, your plan can be adjusted so you keep making progress rather than stopping altogether or trying to follow a plan that no longer fits.
In-person sessions prioritise quality movement, appropriate intensity, and focused work. Depending on your goals, this can include strength training, conditioning, power and speed work, and specific exercises to support injury rehab and resilience. You will be coached through each part of the session so you understand what you are doing and why.
All sessions are held on-site at the WeTrain Gym in Harpenden. The address is Unit 2, Southdown Industrial Park, Harpenden AL5 1DZ
Online coaching provides you with a structured training plan to follow in your own time. You receive clear guidance on exercises, sets and reps, and how to progress. Regular check-ins allow you to ask questions, share feedback, and adjust the plan if needed, so you are not left guessing or training without direction.
Progress is monitored through performance in your training, your feedback on how you are feeling, and for in-person clients, periodic performance testing where appropriate. The aim is to track meaningful changes that relate to your goals, rather than chasing numbers that do not matter to your sport or situation.
Coaching is led by an injury-rehab and performance coach, and is designed to support athletes who want to return to and improve their performance. Training is planned with your injury history in mind, with the aim of building strength, capacity, and confidence in a structured way. This is coaching, not medical treatment, and we always recommend following the advice of your healthcare providers alongside your training.
Training is planned to build performance while managing load appropriately. This means choosing exercises and progressions that match your current level, avoiding unnecessary spikes in training stress, and paying attention to how you respond to the work. The goal is to help you perform at a higher level with better preparation, not to push you for the sake of it.
If something feels wrong or you are unsure, you are encouraged to raise it as soon as possible. For in-person clients, this can be addressed during sessions. For online clients, this can be discussed during check-ins so adjustments can be made where needed.
Training frequency depends on your goals, sport, other commitments, and current capacity. Some athletes will train multiple times per week; others will need fewer sessions that fit around a demanding schedule. The key is that the plan fits your life so you can apply it consistently.
Access to a well-equipped training environment provides more options, but effective coaching can still be delivered with more limited equipment. When setting up your plan, we work with what you have available so your programme is realistic and achievable.
We expect honest communication, a willingness to learn, and consistent effort within your circumstances. In return, you can expect structured coaching, clear guidance, and a professional approach that respects your goals and time.
There is no fixed duration. Some people work with a coach through a specific period to prepare for competition or return from injury; others stay in coaching for longer to keep progressing with strength, conditioning, and performance. The focus is on continued development rather than quick, short-term fixes.
