The Semiotics of Logos II - More Lookalikes

I happened to have seen these two logos within an hour or so of each other yesterday and I was struck by the similarity between them. While I had seen them both before and am familiar with them, I had never noticed how alike they are.

It reminded me of the similarities between the Obama and Pepsi logos which I previously wrote about in The Semiotics of Logos - Obama and Pepsi are Lookalikes.

Has anyone else ever noticed the resemblance?

It is interesting that for how alike they are, what they represent are quite different endeavors.

Though, I suppose if you get right down to it, they are both about exercising (albeit different parts of the body).
