I was going to say "jumping jacks," but then I decided not to be a smarta**.
Seriously, tho, I voted "no," but only based on a narrow reading of the question. More broadly speaking, the only reasonable answer is "yes," I think, because sila is a crucial warmup for any meditation practice.
But on another level, I'm not sure how a person can draw a clear distinction between the "warmup" and the "meditation." Some of the warmups that you have described sound like forms of meditation to me.
