Last night, my new fencing jacket and shoes got their initiation, and it turned out WELL. I didn't have as much knee pain as when i tested out the Vibrams. My "muscular energy" seemed good, which implies that all the little energy-factories were chugging along happily burning fats/ketones ... or whatever they wanted to burn. My "rate-limiting" parameters were that i was functioning on less-than-optimal sleep, and that i'm old and out of shape. ;-) And i sweated like a pig! Good workout!
This morning i WAS a bit stiff! I drank my morning java in a very hot bath, and now i can feel that i worked my legs and right arm, and various torso muscles. It's too bad i won't have a chance to do it again for a week and a half, but my twice-delayed trip will interfere. I'll just have to make myself do series-es (what IS the plural of series?) of advances, retreats, lunges and ballestras to remind my legs of their new responsibilities, and to work on the tightness in my right shoulder which i don't remember being an issue when i fenced before.
I'm not fooling myself about improving my "game" very much -- i'm not expecting to take the senior fencing world by storm! :-) But as Mark has always pointed out, getting exercise is not nearly as beneficial if it's a chore rather than PLAY ... as it ought to be!
