We believe Personal Training means structured programming, expert guidance, and measurable progression rather than guesswork. Here’s how it works:
Get in touch to discuss your goals, availability and current training experience.
We take time to understand your goals, experience and current ability, whether you’re focused on general fitness or athletic performance.
Your movement, strengths and limitations are assessed so your training is built on solid foundations.
Each session is coached in real time at our Harpenden gym, with cues, corrections and progressions matched to your level.
Training evolves as you improve, scaling from foundational work through to more advanced performance training where appropriate.
Over time, you’ll not only get fitter and stronger, but also more confident in how you train and move.
If you’re based in Harpenden and want professional guidance with your training, booking an assessment is the first step.

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.
I’m Dennis, a rehab and performance coach helping driven, ambitious athletes unlock higher levels of fitness, resilience, and confidence.
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.
If you want to perform better, move without pain and build strength that lasts, the next step is simple.
Start your journey today and see what you’re truly capable of.
