For a change of pace today, I stuck in a Rodney Yee yoga DVD.
Strangely enough, I found it to be at once too easy and too hard. The flow of the moves was serene and not at all exhausting -- it was almost as low-key as the movements in P90X X Stretch. Yet at the same time, I struggled with my technique, and my balance and lunge poses were more wobblier than I like.
Still, all in all, I can't complain; it felt great to do yoga this morning instead of pounding my body and risking an overuse injury.
