After the lack of focus on day 13 I managed a pretty focused practice on day 14. So much so that I found afterwards my left knee was quite sore. On day 15 I was taking it easy on my knee, but also trying to get my practice done quickly. It was sort of a sprint yoga. I breathed fasted and so held poses for less time. This was nowhere near as hard as a regular session. Yesterday on day 16 I found that my left knee was much better but that something in my left inner thigh was sore. I did a very very relaxed practice and nothing seems worst.
Now I need to figure out about rest days. I think I probably do need to schedule them in. It turns out the when people talk about a daily practice, they do not actually mean daily practice. Everyone seems to be taking Saturdays off! I will be following their wisdom. Which means tomorrow I get a day off. Maybe I will spend the time to write a fuller yoga post rather than a log of what I did that day.
