Looking for more than just another piece of gym equipment? The REP FITNESS Stone Sandbag Trainer is designed for athletes who train with purpose. Available in six weight options from 50 to 250 lbs, this rugged, round sandbag mimics the feel of lifting an atlas stone — forcing you to engage your entire body, challenge your stability, and develop raw, functional strength that carries over into sport and daily life. Engineered for performance, this isn't a sandbag that quits. It's made from military-grade 1000D Cordura, known for its abrasion resistance and water repellency. Triple-stitched seams deliver maximum durability, allowing you to slam, drop, drag, and carry your bag without fear of tearing or premature breakdown. A double-Velcro closure system ensures your filler stays securely sealed inside, even through the most intense workouts. Whether you're a Cross fit athlete, strongman competitor, or garage gym grinder, the REP Stone Sandbag is built to push your limits. Its awkward, round shape makes traditional lifts — like squats, cleans, and carries — exponentially harder by challenging grip, core strength, and overall control. Unlike machines or barbells, this bag demands more from every muscle, helping you develop the kind of power that translates beyond the gym. Choose your challenge. With weight capacities ranging from 50 lbs up to 250 lbs, the Stone Sandbag grows with you. Start lighter for speed and volume, or go heavy for brutal strongman-style training — the progression is yours to control. And with a clean, minimalist design and unfilled format, it's easy to store, transport, and fill to your ideal load.
