DB Lateral Raise

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

DB Lateral Raise:

Stand with a DB in each hand. Raise the DB’s to the side until they are just above parallel to the ground, or just above shoulder height, pause, lower the DB’s back down, pause, and return to the top position. This is the range, and remember the longer pauses.

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....
