Strong Humans

We are a small family business based in Twickenham. We started making sandbags on the dining table and our ethos is pretty basic - we like to keep it simple!

Functional training. This phrase is thrown around in many different training arenas and is often made out to be technical and complex, which it does not have to be.

Simplicity is key. Shifting load through basic movements has always been an effective way of improving strength and overall well-being.

Our kit is crafted with one goal – to make you stronger, healthier and happier in the most simplistic and functional way.

We use 1000 denier Cordura, Nylon, PU Coated (polyurethane coated) to be waterproof. It is very hard-wearing fabric and has excellent anti abrasion properties. All seams are triple stitched at a minimum using twisted bonded and lubricated multi-filament polyester thread which has excellent UV, rot and mildew resistance.

For other component parts we will always select what we believe to be the highest quality and most robust parts such as Velcro brand hook and loop, and polypropylene webbing (straps) with a break strength of 1000kg, high mildew and rot resistance and high abrasive quality.
