Well, I confess my two-minute plank is on stiff arms. I'm sure I couldn't do that on my forearms. But I'll give it a shot.

The Plank Challenge involves side-planks and other variations. I'm hopeless with side planks. But maybe I'll give it a shot!

I'd really like to report progress with this. In fact, just for the sake of science, for a month or so, I may do ONLY Plank workouts instead of my 3x/wk total body resistance training. See if it accomplishes "the same thing" in less time.

For today, forearm plank. I'll let you know.
