To swim better, we have to swim more efficiently. While good technique is the foundation of efficient swimming, it is difficult to achieve by simply swimming lap after lap. Ongoing stroke problems leave many people feeling unrewarded. Therefore, swimming drills are a fundamental and ongoing element of practice at all levels of the sport.<p> Following the successful book <i>100 Best Swimming Drills</i>, swimming coach Blythe Lucero has compiled another collection of the most effective swimming drills in <i>100 More Swimming Drills</i>. The purpose of each drill is clearly defined as a swimmer and focus on a specific goal while practicing. Each drill is explained step by step. 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.
