{"product_id":"emst150-expiratory-muscle-strength-trainer","title":"EMST150 Expiratory Muscle Strength Trainer","description":"\u003cp\u003eThe EMST150 functions like a hand-held “weight machine” for your respiratory system. It uses a calibrated pressure relief valve to apply a resistive load to expiratory muscles, stimulating strength gains much like traditional strength training does for skeletal muscles. Its adjustable pressure setting (30–150 cmH₂O) allows users to measure progress and increase challenge over time. Compact, lightweight, and portable, it can be used at home, at the gym, or while travelling.\u003c\/p\u003e","brand":"Aspire Respiratory Products","offers":[{"title":"Default Title","offer_id":42648083922990,"sku":"9357308549","price":197.0,"currency_code":"AUD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0604\/4319\/7486\/files\/emst150-460x460-1.png?v=1787531177","url":"https:\/\/shop.superrehab.com.au\/products\/emst150-expiratory-muscle-strength-trainer","provider":"Super Rehab Shop","version":"1.0","type":"link"}
