Here's a look at one of my favorite homemade training aids:
To make your own Streamline Sticks:
1. Cut a piece of 1" PVC tubing to match the width of your lanes.
2. Thread a piece of 1/8" diameter rope through the PVC, leaving about 1' of rope hanging out either way.
3. Tie a 1-pound weight (SCUBA weights work well) to each end of the rope. These weights will drape over the lane lines to hold the Streamline Stick in place.
4. You are ready! Position them on the lane ropes (put a traffic cone on the pool bottom so that swimmers can judge the Stick's location) and away you go!
