Sean Flannery
Sean built SFX on a simple belief: fitness is for everyone. It doesn't matter if you've never stepped foot in a gym or if you train every day — what matters is showing up and doing your best.
We focus on creating a welcoming, ego-free environment where the everyday person can build strength, improve their health, and most importantly, enjoy the process with a great community behind them.
Our approach is straightforward: show up, move well, and stay consistent. We focus on teaching proper technique and movement quality in every single class, ensuring you get a great workout safely.
Whether you're looking to keep up with your kids or just want to feel stronger and healthier, the foundation is the same. We adapt the movements to fit your ability, so you always get the right workout for you.
SFX isn't just a gym; it's a "Band of Brothers" environment where every member is willing each other on. Located in Rathcormack, we provide the elite equipment you'd find in top-tier London clubs, right here in Sligo.
Whether you're hitting the sled track or the functional rig, you're training in a space built for results, surrounded by a community that respects the work.
Where Work Gets Done.
A world-class facility built for real performance. No fluff, just the best equipment in Sligo.
