It’s already quite hot and humid in my apartment, and it’s now 5:20 in the morning, and I’m already sweating. All the exercise people tell us that we need to sweat, and elevate our heart rate, for a certain amount of time before the benefits of exercise kick in. If that’s the case, more than half of my taiji workouts do nothing (Form, five golden coins, eight pieces of silk this morning… and I was reminded of another one that I have knowledge of in a dream [thanks, segmented sleep!] last night.) But I feel like more and more of them are getting to this point of being “light to moderate exercise” — that is, I’m getting a workout, not just moving around in some poses.
