Okay, this morning was a training workout. Two words: "core body." One word: "ouch." He had me doing some twisted and painful things that required concentration, abdominal exertion and balance--we're talking, for examble a bridge and leg curl on my back with my feet up on a big rolly ball. Twisting silliness with a heavy ball while perched precariously on my ass. There's much more, but you get the idea.
I expect substantial pain tomorrow.
