What Filler Should I Use?\u003c\/h4\u003e\n\u003cp\u003eKiln-dried sand is the standard recommendation — it's dense, inexpensive, and doesn't shift excessively once the bag is packed. Avoid moist or garden sand, which can clump, add unpredictable weight, and degrade the inner liner over time.\u003c\/p\u003e\n\u003ch4\u003e2. Can I Adjust The Weight After Filling?\u003c\/h4\u003e\n\u003cp\u003eYes. The filler flap and closure system are designed for repeated opening and refilling. You can add or remove filler to adjust the weight as your training progresses.\u003c\/p\u003e\n\u003ch4\u003e3. Is This Suitable For Drops From Height?\u003c\/h4\u003e\n\u003cp\u003eThe bag is designed to withstand repeated drops as part of normal training — atlas stone loading and platform work inherently involves dropping the bag. The double-layer construction and triple-stitched seams handle this. Dropping from extreme heights onto sharp surfaces or edges will eventually cause wear — this applies to any textile equipment.\u003c\/p\u003e\n\u003ch4\u003e4. How Does This Compare To A Real Atlas Stone? \u003c\/h4\u003e\n\u003cp\u003eThe training demand is similar — the round shape, the lack of handles, and the awkward grip challenge replicate the core difficulty of a stone. The key differences are: the sand stone is adjustable in weight, far lighter to move between stations, can be used indoors, and can be trained solo without risk of damaging flooring. For competition athletes, training on both is ideal. For athletes training alone or without a dedicated platform, the sand stone covers the movement pattern fully.\u003c\/p\u003e\n\u003ch4\u003e5.
