Does my routine unlock other choices besides strength and yoga? I would love to set up a routine with arobics too.

No, the "My Routine" only includes the Yoga and Muscle exercises, which is think is a real shame. It would be great to be able to save a complete workout.

I thought that was strange, as the "Wii Fit routines" (the ones you can do targetting various areas) include the games. If you combine a few of those, you get the games, muscle workouts, and yoga, but a great deal of them include the exercises I don't like...
