grammpaula: I think that's wonderful you signed up with your daughter. A couple of years ago my mom and I signed up - needless to say, neither of us lasted very long.
I completely forgot about this, but just remembered maybe half an hour ago lol.
I signed up for the 2007 challenge, and I e-mailed it to my mom.
We did go to a Bally's (a few times before we just stopped all together). I went a couple more times than she did, but I didn't find it so much as the employees there, but I found it very intimidating with the other gym goers.
I don't remember the "sign-up" staff as I believe this was the 2005? one. I do remember though that one of the guys taking me around, showing me the ropes, was absolutely awesome. I suppose it just really varies.
You are right, though, there is nothing wrong with working out at home
