Finis Posture Corrector Black Yellow

The Finis posture corrector promotes correct alignment of the head and spine, being the key to an efficient swimming stroke. When secured to the rear centre of the head, the device must be undetectable until the swimmer exceeds the recommended posture range. Keeping the head in the correct position throughout the entire swimming movement corrects the alignment of the spine, which raises the hips and leads to a decrease in endurance and an increase in kick propulsion.Features:- Improves body alignment, decreases endurance and increases propulsion - Can be worn with or without glasses - Provides instant feedback to swimmers if their head position is incorrect - Virtually undetectable until the swimmer surpasses the ideal head position - Helps with freestyle technique, back, breaststroke and butterfly
