{"product_id":"ab-trainer-core-strength-fitness-crunch-machine","title":"Core Strength Crunch Machine","description":"\u003cp\u003eFloor crunches are limited by the thing they are supposed to train. Once your neck and hip flexors take over, the abdominal work stops and the repetitions become decorative. The Core Strength Crunch Machine from Cozy Crest supports the head and fixes the movement path, so the load stays on the muscles you are trying to work.\u003c\/p\u003e\u003cp\u003eGuided movement also makes the exercise repeatable. On the floor, no two crunches are quite the same, which makes progress hard to judge. In a frame, the range is consistent, so you can compare one session to the next honestly and add resistance when the current setting stops being difficult.\u003c\/p\u003e\u003cp\u003eThree versions are available across resistance levels and frame sizes. Assemble fully and check every fixing before first use, then re-check periodically. Warm up before working, keep movements controlled rather than fast, and speak to a doctor or qualified trainer before starting if you have any back, neck or joint problems.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003eProduct type: Abdominal crunch machine\u003c\/li\u003e\n\u003cli\u003eBrand: Cozy Crest\u003c\/li\u003e\n\u003cli\u003eMovement: Guided, fixed range of motion\u003c\/li\u003e\n\u003cli\u003eSupport: Head and neck support\u003c\/li\u003e\n\u003cli\u003eVersions: Three options across resistance and size\u003c\/li\u003e\n\u003cli\u003eSafety: Check fixings before use; consult a professional if you have back, neck or joint problems\u003c\/li\u003e\n\u003cli\u003eBest for: Home gyms, core training, consistent progression\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Cozy Crest","offers":[{"title":"6 In 1","offer_id":53708480577812,"sku":"SKU_1768031373633_439","price":106.99,"currency_code":"USD","in_stock":true},{"title":"8 In 1","offer_id":53708480610580,"sku":"SKU_1768031373633_746","price":120.99,"currency_code":"USD","in_stock":true},{"title":"10 In 1","offer_id":53708480643348,"sku":"SKU_1768031373633_665","price":188.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1027\/1975\/0420\/files\/hf_20260824_034201_e9ca84fe-67b9-48fc-99c7-f6ed7abc4ba0.png?v=1787543026","url":"https:\/\/cozycrestliving.com\/products\/ab-trainer-core-strength-fitness-crunch-machine","provider":"Cozy Crest","version":"1.0","type":"link"}
