Ok, I tried out the yoga on Wii Fit Plus. Did all 18 that I have opened for 36 minutes. Worked up a sweat but if just felt to darn easy. Tried a yoga vid on Netflix and gave up after 10 min.
Wound up doing an hour total on Wii Fit today. Not bad. Worked up a good sweat and my meals over the past few days have been on track too. Now that I'm out for the summer, I think I'll be able to get in a lot more exercise.
