Swimming pull buoy.
perfect postition: practice body position with a pull buoy to practice an efficient, competitive stroke while also building upper body strength
upper body training: hold the buoy between your legs to isolate your arms, shoulders, and back, and take your conditioning to the next level
swim longer: let your legs rest instead of flutter kicking, so you can train longer for that perfect technique
craft your stroke: with a pull buoy, you can focus on building efficiency and conditioning without dragging your feet
breath control: master your breath discipline and improve flip turns with long course swim practices
