Bench Press - WG, feet up

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

Bench Press (WG, feet up)

Lie on the bench press. Raise your feet up, bend the knees and cross the ankles. Take a wide grip on the bar, and lower the bar to the bottom of the neck/top of the sternum. Always go down to the same point on the base of the neck each time, and pause there.

Bench press (WG, Feet up)

Lie on the bench press. Raise your feet up, bend the knees and cross the ankles. Take a wide grip on the bar, and lower the bar to the bottom of the neck/top of the sternum. Always go down to the same point on the base of the neck each time, and pause there.

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 one 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....
