DB Pullover (1 DB in each hand)

In 2000 (and on a few other occasions) I published and claimed copyright on this exercise description (bolding added now):

DB Pullover (1 DB in each hand) :

Lying on a bench with your head at one end. Have the arms go over the end of the bench. In this case, lower the DB’s down as far as you can stretch, pause, and then lift them back up to the starting position, which should be short of vertical. Aim to keep the DB’s even during the exercise, but not touching. If this movement has a habit of aggravating the joint, start off with less range and ease into the range with each set.

I was conducting research and I came upon the following exercise in a publication copyright claimed by another 'author' at a subsequent date (bolding added):

And I said to myself: “That looks familiar!” So I cross-referenced it and I said to myself: “Wow! No wonder that looked familiar!”

And I came upon this description another two more times by the same 'author' in different publications.

I noted that the use of this description was in the absence of credits or references to the origin or permission to use from the original author (myself), and that the 'author' claimed copyright....
