About us
Welcome to The House of Gainz — Grantham’s newest industrial-style gym, built for serious training.
Located in Alma Park industrial estate, we’ve created a space where lifters, athletes, and everyday grinders can train hard, push limits, and build real strength in a no-nonsense environment.
Our team
At The House of Gainz, we’re more than just equipment — we’re powered by passionate people who live and breathe training. Meet the team behind the grind.
