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.

What is a Strongman?

Strongman equipment trains raw, functional strength through odd-object lifting, carrying, and loading — atlas stones, yokes, farmer’s handles, sleds, logs, and tires — rather than the fixed, balanced resistance of a barbell. It’s a fit for lifters who’ve plateaued on conventional strength training and want to build the grip, bracing, and full-body coordination that competition strongman and functional fitness demand, or who simply want the most direct training carryover to real-world lifting and carrying tasks. Most pieces are bulky and some (tires, natural stones) are sourced or repurposed rather than bought outright, so plan for storage space and, in a few cases, DIY sourcing as part of owning this equipment.
