VALD Dynamo overview

Meet Your 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.

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.

Frequently Asked Questions

Performance testing uses objective data to assess strength, power, and movement efficiency. It helps us understand how your body performs now, so training decisions are based on facts, not guesswork.

We use the VALD DynaMo system to measure force output and side-to-side differences across key muscle groups. Testing is quick, non-invasive, and tailored to your sport or goals.

Not at all. While it’s ideal for Hyrox and competitive athletes, performance testing is equally valuable for rehab clients, general training, and anyone who wants smarter, safer progress.

We typically test at the start to set a baseline, then retest at key points in your programme. This allows us to track progress, adjust training, and prove what’s improving over time.

No. Testing is designed to establish your current baseline, not judge performance. It works for beginners through to competitive athletes.

Wear comfortable training clothes and trainers, stay hydrated, and avoid intense exercise for 24 hours beforehand for the most accurate results.

Yes. You’ll receive clear results with explanations and practical training recommendations so you know exactly what to improve next.
