If you've been doing the 1 mile for 2 months, you might be more ready than you think for the 2 mile. I have the 1 & 2 mile express DVD. I started in late December with the 1 mile express, but by January I was ready for the 2 mile. I've stuck with the 2 mile ever since. It's tough but definitely worth it... and it's getting easier the longer I do it.

I've thought about moving up to the 3 mile, but I'm not sure I want to give it the extra time. I can't even begin to imagine the 4 mile!!!
