Thanks for answering my question, Guillaume. I've definitely seen doctors and gone to physical therapy about my compressed disc - it's more or less something I have to live with and manage. Sounds like Wii Fit Adventure might be modifiable enough to where I could possibly avoid aggravating it while having an in-home routine during the winter when I get a little more lazy about driving to the gym (who wants to go outside when it's below 10 degrees?).
