WTG, Barb on the 2 minutes! I could do that a few years ago, but I know I'm not in quite the same shape as I was then. It's amazing how quickly the body will rebound, though, with consistent effort.

I'm not sure where I saw the idea to incorporate a short rest between 2 holds, and have no idea if it expedites improvement, but we'll see.

Marvin, I liked that video. While I can do full planks ok, those side planks are killer. Will be adding them, probably starting with knee/arm, and building up. It's only 5:30 here, will report back after my Planks du Jour.
