The Posture Trainer promotes correct head and spine alignment, which is key to an efficient swim stroke. When secured to the back center of the head, the device should be undetectable until the swimmer exceeds the recommended posture range. Keeping the head in the proper position throughout the entire swimming motion corrects spinal alignment, which elevates the hips, leading to a decrease in drag and an increase in kick propulsion. The Posture Trainer's versatility allows for use in all four swim strokes and fits comfortably with or without goggles.FEATURES & BENEFITSProper Alignment Virtually undetectable until swimmer exceeds the recommended posture rangeInstant Feedback: Provides tactile cues to inform swimmers of incorrect head positionStroke Efficiency: Improves body alignment to decrease drag and increase kick propulsionVersatile Fit: Can be worn with or without goggles; one size fits allTurn Technique:Prevents a lifted head position prior to flip turns or open turnsErgonomic Contours:Fits securely to head with minimal water resistanceCorrect breathing motion: Reinforces proper breathing technique for butterfly, breaststroke and freestyleAll four swim strokes:Assists with technique for butterfly, backstroke, breaststroke and freestyle INSTRUCTIONSThe posture trainer uses instant feedback to alert swimmers of improper head position and alignment.
