Only all the time!! Like earlier today. I was sitting on my arse, doing nothing, and I thought, I could be on the Wii right now doing a light workout. So, I got up, set it all up, turned the Wii on, got ready for it to do the measuring junk, then it told me the batteries were dead... and i don't have any spare and don't get paid until tomorrow!!!
So yeah, I haven't done a workout today, but the fact that I got off my arse and tried, to me says a lot!! I used to have to really force myself to go it, but now, coz i was bored... I wanted to.
The moral of this story is, MAKE SURE YOU HAVE BATTERIES IN THE HIZZOUSE!!
