Thin Tummy Variations

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

Thin tummy variations :

Description – lay on your back, knees bent, feet flat, place both hands under your belt line with your fingers heading down into the pubic area and the thumbs placed higher up on the upper abdominal region; throughout all the following levels of difficulty, use the fingers to provide feedback that the lower abdominals are contracted, pulling the lower tummy thinner and creating a high level of tension under the skin; and that the upper abdominal region is hollowed, and non-contracted; and that his relationship is held. Should it at any time change or you feel that it is going to change (e.g. upper tummy bulge, pelvis anteriorly rotate, terminate the range or the set. Focus more on how the muscles are ‘set’ than on the pressure of lumbar to ground or position of pelvis, although both are symptomatic of a good ‘set’ position.

Level One – isometric holds – looking for a good set position

Level Two – as above, but lift one leg up, lower it, rest, repeat opposite leg

Level Three – as above, but when you lift one leg up, extend it out as far as control (i.e. set position) allows

Level Four – as above, but start with both knees up, bent to 90 degrees knees and hips, cycling one leg out towards a parallel to ground position at a time as far as the ‘set’ position will allow

Level Five – as above, but extending both legs out together.

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 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....
