Once I was happy with Lightning’s work on Back to pile from heel position on both sides, the next step in the TRT program was having him learn to sit on whistle or verbal cue while coming back from the pile, and then learn to sit while going out to the pile. Those skills are called ”sit to pile.”

I originally planned to call both of those behaviors Step 2 of PRT pile work, but found that they were quite distinct training objectives. So PRT pile work Step 2 is ”Sit to pile,” while Step 3 is ”Sit from pile.” The present post is for Step 2. Step 3 was written later and is therefore out of order in this journal, several posts after the post on Step 4.

As for Step 2, Mike Lardy provides a complete lesson on sit to pile in the TRT video, and since he uses no force in that segment, it can serve as the PRT lesson for sit to pile as well.
