Them. Them up above. They're why I HATE Chermside Shopping Centre.
Anyhooooo... on a less rage-filled note...
I have had total anxiety about any form of exercise for years. To the point that before I moved to England I was so scared to stand up from sitting that I didn't do it unless someone was in the room. I couldn't get to sleep 'cause I thought I might die during the night that my Mother had to sit with me (I was 26) until I fell asleep and I would often wake her up if I woke up. I moved to England to snap myself out of it. I'm still not totally OK, but I can live alone, walk up some stairs at school and generally stand for the 70 minute lessons.
But that's background information. Needed. You probably won't understand the momentousness of the next statement.
I can now participate in Just Dance 2 for 20 minutes straight and earn on average 250 'sweat points' per song. I am dripping by the end of it. And my left fingers are numb (a common manifestation of stress for me.)
I go straight to bed after doing it. Or at least lying down on the couch. I find if I sleep or get distracted by the TV I forget the immensity of the exercise (which I know doesn't sound that much, but I weight almost 150kgs, so it's a big deal to dance non-stop for 20 minutes, even if it's mostly my body and arms) and can get through the rest of the day.
I feel looser, am sleeping better and can breathe easier.
