Over the past 1 year, Venice Weights has revolutionized access to sports equipment and bodybuilding weights with its DIY approach. This revolution has won over many enthusiasts who, from the outset, understood the advantages and potential of concrete weights for their homegym.
However, some skeptics legitimately raised questions about their sturdiness, for example. An aspect that Venice Weights has proved through its drop tests and unanimous customer feedback! But one question that comes up from time to time concerns the precision of a concrete bodybuilding disc.
How can you be sure that 2 weights cast in the same mould will produce two concrete discs with the same exact weight?
Let's start by exploding some preconceived notions! Have you ever wondered about the cast-iron or rubber weights you find in shops or gyms?... No ?... Well, we've done it for you:
According to an American study, “traditional” weights aren't as reliable as you might think... The results are more than shocking:
- A cast-iron weight may differ from the indicated weight by up to 5%.
- Even the best cast-iron weights are up to 2% over or under.
- A rubber bumper can have a 1% difference from the indicated weight.
-
Only professional (and very expensive) weightlifting weights are accurate to within 10 grams.
- Cast iron : From 19 to 21kg > 1kg difference between two weights on the same bar!
- Bumper: 19.8 to 20.2kg > 200g difference between two weights on the same bar!
The greatest inaccuracies increase, in percentage terms, for the lightest disks... A weight difference of this magnitude on the same bar can lead to body asymmetry and long-term injury.
“Before weighing my plates, I usually, but unknowingly, lifted a different weight each week, even though I thought I had the same weight on the bar the whole time.”

When it comes to concrete weights, there's no problem! In fact, that's the advantage of DIY concrete weights for your homegym: the concrete is weighed before it's molded. So you know in advance how heavy your concrete weight disc will be. According to our measurements over the last few years, the wear on a concrete weight never exceeds 1% for properly manufactured concrete. This means that a concrete weight is close to professional standards in terms of precision.
You may still be sceptical about this study, but if so, don't hesitate to go and weigh the cast-iron weights at your homegym or gym and see for yourself... You may be in for a surprise!
Another theory is that gyms have a vested interest in offering overpriced discs/halters... see here (but this is fantasy... or not 😉).
