Since the sport of water polo takes place entirely in the water, swimming skill, mobility and endurance are essential requirements. Effective swimming drills include everything from short, intense swims to longer, slower workouts. 101 Defensive and Conditioning Water Polo Drills features 34 conditioning drills, 11 individual defense drills, 8 two-meter defender drills, 6 defense against the counterattack drills, 15 team defense drills, 6 5-on-6 drills, and nearly 20 goalie drills. Each drill is thoroughly explained, illustrated, and many are diagrammed to make them easy to understand and apply.
