{"type":"firestarter.listing","listing":{"id":"lst_qkT7ZMN_","product_name":"Training Mask - AEROSx Lung Trainer (Respiratory Resistance Device)","category":"Respiratory Trainers","description":"\n\n6 dial-adjustable resistance levels: Turn the resistance valve left or right to dial airflow load on inhalation and exhalation -- progress with you as fitness improves.\n\nMouthpiece-based design: Compact silicone mouthpiece with seated plastic valve creates an optimal seal for breath training -- not a mask, no head strap.\n\nTargets diaphragm + intercostals: Strengthens the primary respiratory muscles to support deeper, more efficient breathing and improved lung volume threshold capacity.\n\nFootball helmet adapter compatible: Optional adapter attaches the AEROSx to a football faceguard so players can train respiratory load during drills and route work.\n\nLightweight + portable: Small enough to take anywhere -- training kit, gym bag, or office desk -- to support 5-minute daily warm-up or cool-down sessions.\n\nThree colorways: Black, White, Red. Easy clean -- rinse under the tap or wipe with mild detergent.\n","images":["https://cdn.shopify.com/s/files/1/0508/3670/1334/files/aeros-black.jpg?v=1780589598","https://cdn.shopify.com/s/files/1/0508/3670/1334/files/Artboard5_2x_c787d38b-7506-4935-b128-ce01abba69c4.jpg?v=1780589598","https://cdn.shopify.com/s/files/1/0508/3670/1334/files/leftmouth.png?v=1780589598","https://cdn.shopify.com/s/files/1/0508/3670/1334/files/amz1-aeros.jpg?v=1780589598","https://cdn.shopify.com/s/files/1/0508/3670/1334/files/aeros-sled-pull_b8679d83-ca34-4021-ac1a-3b150ba77406.png?v=1780589598","https://cdn.shopify.com/s/files/1/0508/3670/1334/files/aerosx-4.jpg?v=1780589598","https://cdn.shopify.com/s/files/1/0508/3670/1334/files/animated-black.gif?v=1780589598","https://cdn.shopify.com/s/files/1/0508/3670/1334/files/aerosx-3.jpg?v=1780589598","https://cdn.shopify.com/s/files/1/0508/3670/1334/files/animated3_4ef7a4f3-52fb-41f9-907e-6b0736c2ca7f.gif?v=1780589598","https://cdn.shopify.com/s/files/1/0508/3670/1334/files/aerosx-2.jpg?v=1780589598","https://cdn.shopify.com/s/files/1/0508/3670/1334/files/animated-white.gif?v=1780589598","https://cdn.shopify.com/s/files/1/0508/3670/1334/files/aerosx-5.jpg?v=1780589598","https://cdn.shopify.com/s/files/1/0508/3670/1334/files/aeros-white.jpg?v=1780589598","https://cdn.shopify.com/s/files/1/0508/3670/1334/files/aeros-red.jpg?v=1780589598"],"price":39.99,"currency":"USD","in_stock":true,"inventory_qty":29997,"dynamic_pricing":false,"listed_at":"2026-07-03T16:00:56.607Z"},"share_url":"https://firestarter.network/l/lst_qkT7ZMN_","purchase":{"summary":"Live product listing on the Firestarter agent commerce network.
