Catch-up Freestyle:
This technique/drill is not based on sound mechanical principles, and should not be taught to beginning competitive swimmers. In order to 'correct' a swimmer who has learned a pronounced catch-up freestyle, try the following:
Have the swimmer to swim 'waterpolo freestyle' (head out of the water with an actual water polo ball). No one (that I know of) can swim catch-up using the waterpolo freestyle...do this for several lengths.....after the 10th 25 (with recovery built in) have the swimmer swim waterpolo freestyle with the ball for 12 yards....after that point simply drop the head in a normal prone position, and have the swimmer swim freestyle (no breathing) to the wall....if you do this enough...and it will have to be done a lot...you can begin to 'change/alter/correct' a freestyler from catch-up to 'hands opposed' freestyle.
