ABOUT US
Grafters Ironworks Gym — Built for Real Training
Tucked beneath the iconic Empress Building in Mexborough, Grafters Ironworks Gym is more than just a place to work out — it’s a no-nonsense, community-driven space where strength is forged daily. With over 4,500ft² of ground-level gym floor, fully loaded with serious kit, it’s the perfect home for lifters, fighters, and everyday grafters.
Founded by health and fitness enthusiast Mike Hobson, this family-run, independent gym offers a refreshing alternative to the usual cookie-cutter chains. No gimmicks. No fluff. Just proper equipment, serious workouts, and expert support.
Purpose-Built Layout for Serious Results
Instead of cramming cardio machines into every corner, Grafters features an open-plan layout intelligently divided into dedicated training zones:
- Legs
- Back
- Chast
- Abs
- Cardio
- Boxing
Whether you're a casual gym-goer or a competitive lifter, you'll find everything you need — including over 4,500lbs of plate weights, Olympic-standard bars, super-heavy dumbbells, and more elite-grade equipment.
Comfort All Year Round
Thanks to its basement location, Grafters stays cool in the summer and comfortably warm through the winter — unlike those cold, draughty warehouse gyms.
Modern Facilities with Old-School Grit
A recent refurbishment means the gym now boasts luxury male and female changing rooms, showers, and secure lockers — proof that we never stop reinvesting in your training experience.
