Today I did the 60 min. section of Bob Harper's "Yoga for the Warrior" - though it's really more like 56 min., and the first two and last ten are just stretching.
Still! Challenging and relaxing at the same time. There's a lot to be said for power yoga.
p.s. We're still dealing with the cold-that-never-ends at our house. Ugh. It's throwing off our schedules, hence the couple of days without a workout.
