{"product_id":"100-best-swimming-drills-book-blyth-lucerno-9781841263373","title":"100 Best Swimming Drills","description":"Achieving better  swimming is  a  matter  of  swimming efficiently. While proper technique is the foundation of good swimming, it is often difficult to isolate a technique problem by simply swimming laps. Stroke flaws can slow a swimmer's progress and can even lead to injury if continued over time. For these reasons, swimming drills have become a fundamental part of training at all levels of the sport.  Drill  practice  is  a  swimmer's  primary tool  in  developing  better stroke technique. The book is organized into sections covering the four competitive strokes: freestyle, backstroke, breaststroke and butterfly. Each drill is explained step by step and accompanied by comprehensive diagrams. Drill feedback charts are included to help swimmers identify problems and make modifications. Underwater and  surface  photographs  give  swimmers  optimal  images  to emulate as they practice.","brand":"WoB","offers":[{"title":"GB \/ VERY_GOOD \/ INTERNAL","offer_id":49612913836305,"sku":"GOR007872925","price":13.99,"currency_code":"EUR","in_stock":false},{"title":"GB \/ NEW \/ GARDNERS","offer_id":49731896246545,"sku":"NGR9781841263373","price":0.0,"currency_code":"EUR","in_stock":true},{"title":"US \/ GOOD \/ SBYB","offer_id":50043624194321,"sku":"CIN1841263370G","price":0.0,"currency_code":"EUR","in_stock":false},{"title":"GB \/ GOOD \/ INTERNAL","offer_id":50290776342801,"sku":"GOR009724704","price":7.39,"currency_code":"EUR","in_stock":false},{"title":"US \/ VERY_GOOD \/ SBYB","offer_id":50765009584401,"sku":"CIN1841263370VG","price":0.0,"currency_code":"EUR","in_stock":false},{"title":"US \/ NEW \/ INGRAM","offer_id":51391556256017,"sku":"NIN9781841263373","price":0.0,"currency_code":"EUR","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0784\/4072\/6801\/files\/1841263370.jpg?v=1750930566","url":"https:\/\/www.worldofbooks.com\/de-de\/products\/100-best-swimming-drills-buch-blyth-lucerno-9781841263373","provider":"World of Books ","version":"1.0","type":"link"}
