Hi Cindy,
I had actually asked that same question a month ago in the new riders section, you can look up the thread there. But someone had suggested imagining that you are trying to scrape something off the bottom of your shoe, and keep your foot relatively flat. This helps immensely on hills.

I have noticed since I started doing this and less toe pointing that my calves aren't as nicely toned anymore, but I've gotten much more definition in my quads...I take this as a sign that I'm doing it right.


Cheers
Emily
