Adjustable Atlas Stone
Calculate the final weight of a hollow atlas stone based on its diameter, core size and the granular material used to fill it. Adjust the sliders and watch the result update live.
What is the adjustable atlas stone?
The adjustable atlas stone is my prototype with a hollow core that you fill with the material of your choice. The atlas is filled with sand, steel granulate or lead granulate. Instead of one fixed weight, it covers a wide range — from lighter pulls for technique to competition-heavy.
One stone replaces a whole set of fixed-weight stones. Save space, money and logistics — and always have the exact weight you need on hand.
Variable weight
Dial in exactly the weight you need — warm-up, technique work or a competition attempt. Progress gradually and build strength the smart way.
One stone, many setups
Instead of multiple stones at different weights, one adjustable atlas covers them all. Less storage, less hassle, more options.
Who is it for
Home gyms, training clubs, events and competitions — anywhere you want flexibility without using a large range od different stones, dealing with the weight, logistics, cleaning and its maintenance.
How to use the calculator
Pick the atlas diameter and core size, choose the material and use the slider to set the fill percentage. The resulting weight is calculated live.
