As discussed in part I, having distal thumb extension can increase drag and eddy currents. This occurs when the swimmer tries to maximally extend their fingers to increase their surface area for the catch. To break this habit, the swimmer will have to actively flex the distal part of their thumb. This will be a long process, but can make a big difference in drag. Instruct them to hold their thumb firm and STRAIGHT!
