Hybrid Stone Molds

Developed by Rob Orlando at Hybrid Athletics in Connecticut, Hybrid Stone Molds have been trusted by Strongman athletes for the better part of a decade as a way to produce their own custom-sized Atlas Stones, be it for personal use or as complete sets for multiple athletes in a larger facility.

Unless you lived down the street from an Atlas Stone manufacturer, acquiring these implements in the past generally meant taking on astronomical shipping costs or working out a complicated pick-up. These durable, relatively lightweight plastic molds solve this issue while still enabling a wide range of training options. Molds can be purchased from as small as 10” in diameter (approx. 35 LBS) to as large as 19” (300 LBS), and setting the stones is quite simple.

Each Hybrid Stone Mold divides into two hemispheres. To create an Atlas Stone, start by opening and cleaning the inside of each hemisphere with a lubricant, then re-connect the halves securely via zip ties and position the sphere on a stable base (such as a turned over tire). Create your concrete mix + water at the desired weight corresponding to the mold, then add the mix to the mold, ensuring that the entire mold is filled.

After three days, you can use a tap stick to wedge off the hemispheres and reveal the Atlas Stone, which will also include a Hybrid “H” logo. Any unwanted edges can be smoothed over with sandpaper to complete the process.

Available Stone Mold Sizes

Please Note: Weights listed for each stone mold size are estimates. This can vary due to variation in concrete and the process used to make the stone.
