Our Story

IronBox started in 2019 when Coach Ryan Teo signed the lease on a raw warehouse space in Tanjong Pagar. No mirrors, no air-conditioning, no machines — just a barbell, some plates, and a pull-up rig. The first members trained in 35-degree heat with the loading dock doors open. Five years later, IronBox has grown into one of Singapore’s most competitive CrossFit boxes, producing Games qualifiers, national-level lifters, and hundreds of everyday athletes who discovered what they’re capable of when the programming is smart and the coaching is relentless.
