I'm not taking anything away from what was just said.

In the pushup example...I don't know how to explain it but "tightness" wouldn't be the word I would use, but I can't think of another.

"Braced" is a good word. You won't feel the "tightness" in your muscles (I would say, I feel a "slow drag," like when a big fish takes your hook and goes), but you will feel it around your joints.

I only wanted to add that just in case you were thinking, "am I not doing it right?"
