Use Streamline Sticks
at 7yd distance from each wall. Put two at each location, effectively
blocking off the entire lane. Swimmers have to kick out 7yd off the
wall, swim 11yd, and then kick the final 7 yd underwater, do an open turn
and do it again! Feel free to change up the underwater distance for a
more or less challenging set.
