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\/span\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cb id=\"docs-internal-guid-04a5f1ac-7fff-897f-56ca-0462742c159f\"\u003e\u003cspan\u003eWhat weights are available?\u003c\/span\u003e\u003cspan\u003e \u003c\/span\u003e\u003c\/b\u003e20kg, 40kg, 60kg, 80kg, 100kg, 120kg, and 140kg\u003cb id=\"docs-internal-guid-04a5f1ac-7fff-897f-56ca-0462742c159f\"\u003e\u003cspan\u003e.\u003cbr\u003e\u003c\/span\u003e\u003c\/b\u003eStarter Set consists of one of each: 20kg, 40kg, 60kg \u0026amp; 80kg\u003cbr\u003eAdvanced Set consists of one of each: 100kg, 120kg \u0026amp; 140kg\u003cbr\u003eFull Set consists of one of each: 20kg, 40kg, 60kg, 80kg, 100kg, 120kg \u0026amp; 140kg\u003cbr\u003e\u003c\/p\u003e\n\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Strength Shop","offers":[{"title":"20kg","offer_id":58212865868160,"sku":"SAND-ATLAS-STONE-20","price":44.95,"currency_code":"EUR","in_stock":true},{"title":"40kg","offer_id":58193800659328,"sku":"SAND-ATLAS-STONE-40","price":49.95,"currency_code":"EUR","in_stock":true},{"title":"60kg","offer_id":58193800692096,"sku":"SAND-ATLAS-STONE-60","price":54.95,"currency_code":"EUR","in_stock":true},{"title":"80kg","offer_id":58193800724864,"sku":"SAND-ATLAS-STONE-80","price":59.95,"currency_code":"EUR","in_stock":true},{"title":"100kg","offer_id":58193800757632,"sku":"SAND-ATLAS-STONE-100","price":68.95,"currency_code":"EUR","in_stock":true},{"title":"120kg","offer_id":58193800790400,"sku":"SAND-ATLAS-STONE-120","price":78.95,"currency_code":"EUR","in_stock":true},{"title":"140kg","offer_id":58193800823168,"sku":"SAND-ATLAS-STONE-140","price":88.95,"currency_code":"EUR","in_stock":true},{"title":"Starter Set - 20kg 40kg 60kg 80kg","offer_id":58193800888704,"sku":"SAND-ATLAS-STONE-STARTER","price":196.95,"currency_code":"EUR","in_stock":true},{"title":"Advanced - 100kg 120kg 140kg","offer_id":58194024759680,"sku":"SAND-ATLAS-STONE-ADVANCED","price":216.95,"currency_code":"EUR","in_stock":true},{"title":"Full Set - 20kg 40kg 60kg 80kg 100kg 120kg 140kg","offer_id":58193800921472,"sku":"SAND-ATLAS-STONE-FULL","price":413.95,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0619\/0222\/5661\/files\/DSC05309.jpg?v=1780406957","url":"https:\/\/www.strengthshop.ie\/products\/strength-shop-sandball-sand-atlas-stone-20-140kg","provider":"Strength Shop","version":"1.0","type":"link"}
