{"product_id":"the-100-up-exercise-9780957670402","title":"The 100-Up Exercise","description":"Walter G George was a hugely successful runner and athlete. In 1886 he ran a mile in 4 minutes 123\/4 seconds-a record that held for almost 30 years. He devised the '100-Up' Exercise as part of his training, using it to enhance his fitness and improve his running technique. In the early twentieth century he published details of the '100-Up' and they are now reprinted here in full for a new readership. The '100-Up' Exercise has seen a huge revival in the twenty-first century. It is used by many runners to improve their performance and develop technique, but the method can also be used by non-athletes to increase fitness and stamina. Best of all, it's an exercise you can do indoors or outdoors, at home or at work... in fact, almost anywhere.\u003cbr\u003e","brand":"Dormouse Press","offers":[{"title":"Default Title","offer_id":50872997150994,"sku":"9780957670402","price":8.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0831\/4771\/8930\/files\/img_08de50ee-8767-4db0-baeb-c905134f7a9c.jpg?v=1737917065","url":"https:\/\/surprise-castle.myshopify.com\/products\/the-100-up-exercise-9780957670402","provider":"Surprise Castle","version":"1.0","type":"link"}
