The single tubing attachment over 2 fingers challenges the swimmer to efficiently, and effectively hold water on the paddle (hand) through the full range of the underwater stroke. The paddle is most secure on the hand when the paddle is “anchored” on water, and not slipping or wobbling on the stroke. This correct technique maximizes distance per stroke. The GROOVER CHALLENGE is to find that stable hand position to hold water on the paddle through the full range of the underwater stroke. This will come quickly as the single 2 finger attachment helps the hand “find” and “hold” the desired stable position automatically. This is also the goal for butterfly swimming with the GROOVER. It may be necessary to use the 2 tubing positions for single finger insertions on each ½ side of the paddle until the GROOVER CHALLENGE is mastered. The 2 tubing positions each for a single finger may also be necessary for some swimmers in free and back until the GROOVER CHALLENGE is attained. The 2 tubing positions is illustrated for breast stroke swimming on the enclosed tubing illustrations for GROOVER and is recommended only for the learning and adapting stage. **The GROOVER wasn’t designed to be a rigid, flat paddle. It is a flexible paddle designed to adapt to the shape of the hand while swimming.**
