Streamline Sticks are easily among the best pieces of training equipment I have seen in my 13 years of club coaching. We use them weekly to develop the habits and skills to produce consistent underwater dolphin kicking. They force swimmers to kick a set distance off the wall and allow for circle swimming within the lane. Send me an email at firstname.lastname@example.org or just leave your e-mail in the comments below if you are interested in getting your hands on a Streamline Stick and maybe I’ll make a few for Swimming Wizard readers.
UPDATE: The Swimming Wizard has been overwhelmed with responses about these streamline sticks. I am planning to post a video soon that explains how they may be constructed. Thanks! – Ryan
