{"type":"firestarter.listing","listing":{"id":"lst_Nma9SEJn","product_name":"Tibialis Trainer Bar","category":"Strength Training Accessory","description":"The tibialis trainer bar is your first defense against knee & shin injuries.When strong, it protects your knees by absorbing deceleration forces while landing from a jump or pivoting on the field. When weak, it can cause knee pain and hobble-worthy shin splints.Luckily, this tibialis trainer bar is all you KNEE-d. Sorry. Couldn’t resist.Crank out standard tib raises, or use it for hanging hip flexor raises to strengthen your hip flexors. Better yet, bust out some leg extensions or lay supine on a bench to hit those hamstring curls.The eyelet can connect to your Cable Tower or Belt Squat Machine. Or, attach a resistance band to it for heavy eccentrics.\nIMPORTANT: Loading sleeve fits 2” Olympic weight plates only.","images":["https://cdn.shopify.com/s/files/1/0654/3346/9125/files/TIBI-BAR-hero_b2e2c1ac-3d75-4d1c-8438-86136a4bd251.jpg?v=1764592038","https://cdn.shopify.com/s/files/1/0654/3346/9125/files/TIBI-BAR-Gallery_201_1da65976-4d7c-48a9-a290-43d714ac3da7.jpg?v=1764592038","https://cdn.shopify.com/s/files/1/0654/3346/9125/files/TIBI-BAR-Gallery_202_6450b295-7df0-4840-95c8-8dfa96eeaff3.jpg?v=1764592038","https://cdn.shopify.com/s/files/1/0654/3346/9125/files/TIBI-BAR-Gallery_203_61179b3d-f717-446d-8c9e-82b1e36fd01f.jpg?v=1764592038","https://cdn.shopify.com/s/files/1/0654/3346/9125/files/TIBI-BAR-Gallery_205_3f702f3d-3078-4d02-b8cd-c0ab34138b0e.jpg?v=1764592038","https://cdn.shopify.com/s/files/1/0654/3346/9125/files/TIBI-BAR-Gallery_206_1c880f39-ea30-47d0-bf5f-ab9a20b519a1.jpg?v=1764592038","https://cdn.shopify.com/s/files/1/0654/3346/9125/files/TIBI-BAR-Gallery_207_95b4ef10-1404-42df-9cec-3c35ac136391.jpg?v=1764592038","https://cdn.shopify.com/s/files/1/0654/3346/9125/files/TIBI-BAR-Gallery_208_c76e7ba3-b057-4ec1-af59-d4b3adf07f26.jpg?v=1764592038"],"price":84.99,"currency":"USD","in_stock":true,"inventory_qty":9999,"dynamic_pricing":false,"listed_at":"2026-06-18T20:46:45.684Z"},"share_url":"https://firestarter.network/l/lst_Nma9SEJn","purchase":{"summary":"Live product listing on the Firestarter agent commerce network.
