{"product_id":"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.","brand":"Dormouse Press","offers":[{"title":"Default Title","offer_id":48478309318897,"sku":"9780957670402","price":9.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/5433\/7265\/files\/9780957670402_p0.jpg?v=1785900021","url":"https:\/\/shop.barnesandnoble.com\/products\/9780957670402","provider":"Barnes \u0026 Noble","version":"1.0","type":"link"}
