Holy cow, I'm drained. I tried something called “hot yoga” (ホットヨガ) today at a local gym (Inspa in eastern Kyoto, near Sanjo Kawaramachi). I'd never done yoga... it seems to be simple stretching and balance, but “hot yoga” is doing it in a humid room heated to about 36°C (97°F). Fumie had just joined the gym and really liked this particular class.
Considering that I am spectacularly unflexible, I thought perhaps it'd be beneficial in limbering me up, so I thought I'd give it a try. I was not prepared for just how hot/humid it was, though I would have been fine if the class were just 45 minutes, but it was an hour and that last 15 minutes utterly drained me to the bone.
I will sleep well tonight.
