I like the picture because it could be interpreted as someone in either a flexion exercise (like ab curls) or in a back extension exercise (like Swan Dive). Even though it could be seen either way, I prefer to position it in such a way that the back extension is more likely interpretation. For that reason, I like the picture outside the words (as in #6) rather than in the words (as in #7).
Also, I am noticing that I am drawn to circles, so I do like the picture in the circle (#6) better than using it in the word Pilates (#7).
However, I prefer the relative weight of the words better in #7. Pilates feels to heavy in #6.
I do not like the colors. It feels too dark and heavy and even old. The red is too brown. Can we try a different red? I think I would prefer more of an orange-red, a pinker or grey-red might be an option, and maybe even a purple-red. Of course, then the color of the picture would depend on the color of the words.
