{"type":"firestarter.listing","listing":{"id":"lst__jiWSdpa","product_name":"Squat Harness - V4","category":"Rack Attachments","description":"\n\n3-inch main straps for maximum durability: Wider than V3 — distributes load more evenly across the torso and resists wear under heavy, high-frequency training better than narrower strap designs.\n\nRib-area padding: Under heavy loads, the harness tightens against your torso and without padding the straps create significant pressure on the lower ribs. The padding distributes load more evenly for training at high intensities and high volume.\n\nEstimated 950 lb load capacity: Engineered for heavy cable machine training, free weight loading, and resistance band work across the full range of Squat Harness exercises.\n\nChest-only buckle placement: Simplified from V3's two-buckle layout — faster to put on and take off, fewer adjustment points to manage between sets.\n\nTop and bottom D-rings: Multiple attachment points for cables, loading straps, band hook straps, and other Squat Harness accessories — versatile setup for the full exercise library.\n","images":["https://cdn.shopify.com/s/files/1/0508/3670/1334/files/IMG-7678.png?v=1780603586","https://cdn.shopify.com/s/files/1/0508/3670/1334/files/IMG-7679.png?v=1780603586","https://cdn.shopify.com/s/files/1/0508/3670/1334/files/IMG-7680.png?v=1780603586","https://cdn.shopify.com/s/files/1/0508/3670/1334/files/IMG-7681.png?v=1780603585","https://cdn.shopify.com/s/files/1/0508/3670/1334/files/IMG-7682.png?v=1780603586","https://cdn.shopify.com/s/files/1/0508/3670/1334/files/IMG-0899.png?v=1780603586","https://cdn.shopify.com/s/files/1/0508/3670/1334/files/IMG-0910.png?v=1780603586","https://cdn.shopify.com/s/files/1/0508/3670/1334/files/D3135DA0-1F99-4607-91F5-E5B96514862E.png?v=1780603586","https://cdn.shopify.com/s/files/1/0508/3670/1334/files/FBC4400E-E373-4694-A65E-C1F95611AF0E.png?v=1780603586","https://cdn.shopify.com/s/files/1/0508/3670/1334/files/C4A28A63-98A2-4A13-A93C-B93AE99A75C3.png?v=1780603586","https://cdn.shopify.com/s/files/1/0508/3670/1334/files/DE615745-3CD0-45D5-8197-2351960F831E.png?v=1780603586","https://cdn.shopify.com/s/files/1/0508/3670/1334/files/IMG-8878.png?v=1780603586","https://cdn.shopify.com/s/files/1/0508/3670/1334/files/IMG-8880.png?v=1780603586","https://cdn.shopify.com/s/files/1/0508/3670/1334/files/IMG-2106.png?v=1780603585","https://cdn.shopify.com/s/files/1/0508/3670/1334/files/Untitled_2ddd1720-f9ed-44e5-85d4-433f1987dea0.png?v=1780603586","https://cdn.shopify.com/s/files/1/0508/3670/1334/files/Untitled_c2b1b82b-85d5-471a-bd83-edfc0ade1929.png?v=1780603586","https://cdn.shopify.com/s/files/1/0508/3670/1334/files/Untitled_b94299f9-43e3-4643-8d28-3b940b41702f.png?v=1780603586","https://cdn.shopify.com/s/files/1/0508/3670/1334/files/Untitled_046c927b-e422-4105-8d6b-f09daa401477.png?v=1780603586"],"price":249,"currency":"USD","in_stock":true,"inventory_qty":19998,"dynamic_pricing":false,"listed_at":"2026-06-20T14:56:53.468Z"},"share_url":"https://firestarter.network/l/lst__jiWSdpa","purchase":{"summary":"Live product listing on the Firestarter agent commerce network.
