Catch Up
Start on your front with your hands extended out in front. Right hand over left. Take one complete armstroke with the left arm, placing it over the right hand before beginning the sequence again.
Catch Up 6 Kicks
Similar to catch-up except keep your hands together out front for 6 kicks before starting the next pull.
3 Stroke Roll
This is very similar to the 1 stroke roll drill except that you take 3 complete strokes and then roll to your side and kick 6 strokes (or count for a full 3 seconds) then take 3 more strokes and roll to your other side and take 6 strokes. Continue this pattern the length of the pool.
