A 63 year-old kicked my butt

My TKD instructor is out for a few classes so some of the black/red belts are taking turns leading the class. Wednesday was Mary... a gentle-looking soul that I initially took to as she was so nice and welcoming (and the only person older than me)...I figured her to be about 50 and thought it was cool she was there kickin and giving it.

Found out Wednesday, she luvs to spar and has the heart of a drill sergeant. And that she's 63. By the end of class, sweat was rolling down my temples and my sit-ups were shrugs. (Who still does sit-ups? I thought they were long extinct in favour of crunches, planks and almost anything else)
So tonight should be interesting, one of the "kids" (read insanely fit 16 year olds) is leading the warm up and then she's doing the class again. 

I think it's excellent that she started at 59 and kept with it.  I'd luv to think I'm still as engaged and active even if it's not with a combat sport. She is keeping with who she is and not just settling in with her old patterns of things.  And still challenging herself and others.

Speaking of which, oh my...must go drink more water now.
