I dont got room to dance, only room with room, is acupied by a grumpy old half deaf man who watches tv with the volume up so high you can hear it upstairs over games. (thankfully i got a headset for it)
I so wish I could do that, moving my hips and legs and waist is sooo, theraputic for me. My dad gets anoyed at my energy, "its destracting" and thats just going to the kitchen to make coffee.
Ill give him his due, He did help me when My forms fell out and I had mucky gloves on due to garden work

. I got to settle for that as exercise.
I think its great, I find the workout routines soo much like hard work it takes the motivation away. But I can move my hips all night and all day if i got the chance.
anyway, back to your question.
If brushig your hair is relaxing, Id say it counts.
PS, Only chance I get to dance is after my dad goes to bed, And I do it in the dark, and that bright green light from the DVD player, Causes a shadow and I watch that. Not exacly a mirror but........
