{"type":"firestarter.listing","listing":{"id":"lst_EAxnPEio","product_name":"Squat Harness - Premium Adjustable V3","category":"Rack Attachments","description":"\n\nOpen-ended hooks for fast weight loading: Slide weight plates, barbell sleeves, or loading strap hooks on and off quickly without threading through closed loops — speeds up plate changes between sets significantly.\n\nCross straps for spinal load distribution: When weight is attached below via loading straps or cable, cross straps distribute the downward pull across a larger surface area of the torso — reduces localized pressure and supports a more upright posture.\n\nShoulder support loops: Added stability for squats and deadlifts — keeps the harness positioned correctly on the shoulders under dynamic loading conditions.\n\n750 lb maximum recommended load: Compatible with cable machines, resistance bands, trap bars, and barbells for the full Squat Harness exercise library.\n\nV3 vs V4: V4 upgraded to 3-inch main straps, simplified to chest-only buckles, and increased load capacity to 950 lb. Both are capable harnesses — V4 is the current top model.\n","images":["https://cdn.shopify.com/s/files/1/0508/3670/1334/files/Untitled_45.png?v=1780603560","https://cdn.shopify.com/s/files/1/0508/3670/1334/files/Untitled_46.png?v=1780603560","https://cdn.shopify.com/s/files/1/0508/3670/1334/files/Untitled_44.png?v=1780603560","https://cdn.shopify.com/s/files/1/0508/3670/1334/files/IMG-2891.png?v=1780603560","https://cdn.shopify.com/s/files/1/0508/3670/1334/files/IMG-2892.png?v=1780603560","https://cdn.shopify.com/s/files/1/0508/3670/1334/files/IMG-2893.png?v=1780603560","https://cdn.shopify.com/s/files/1/0508/3670/1334/files/150AF00C-527A-41F0-A4BA-F35687F0BE00.png?v=1780603560","https://cdn.shopify.com/s/files/1/0508/3670/1334/files/77791C2F-FB9B-4183-9136-B9DD7C64431E.png?v=1780603560","https://cdn.shopify.com/s/files/1/0508/3670/1334/files/Untitled_24.png?v=1780603560","https://cdn.shopify.com/s/files/1/0508/3670/1334/files/Untitled_23.png?v=1780603560","https://cdn.shopify.com/s/files/1/0508/3670/1334/files/Untitled_25.png?v=1780603560","https://cdn.shopify.com/s/files/1/0508/3670/1334/files/IMG-3625.png?v=1780603560","https://cdn.shopify.com/s/files/1/0508/3670/1334/files/74744966-430C-4205-9415-A16820D02D3F.png?v=1780603560","https://cdn.shopify.com/s/files/1/0508/3670/1334/files/F5B68882-C73D-4D2E-854F-5EBAC6222D2D.png?v=1780603560","https://cdn.shopify.com/s/files/1/0508/3670/1334/files/5CB3F5A0-3792-42DB-9D60-A62C9A01760D.png?v=1780603560"],"price":177.76,"currency":"USD","in_stock":true,"inventory_qty":9999,"dynamic_pricing":false,"listed_at":"2026-06-20T14:56:55.620Z"},"share_url":"https://firestarter.network/l/lst_EAxnPEio","purchase":{"summary":"Live product listing on the Firestarter agent commerce network.
