|Wobble Board-ing my ankles.|
(Hips and glutes to try to get my IT bands back in shape, ankles and arches because I have flat duck feet, etc.)
I am already sore from my first heavy (well, "heavy") weights lifting in a long time yesterday; now all the small muscles in my lower legs are protesting, too.
But I love it. A few sore muscles now means a strong race season down the road, hopefully.
