Can you be TOO flexible???

Well, yes...and no. Yes, but only if you lose body awareness. That happened to me while striking Virabhadrasana I (Warrior 1). I didn't realize it until colleagues pointed it out. What's the big deal? Over time, misalignment can cause serious injuries. A couple things you can do: lay your strap or draw a line down the middle of your mat. For this pose in particular it will help insure you are lining your heals on the same plane. Secondly, practice in front of a full length mirror. At some point you'll want to break away from this so you can bring your thoughts inward, but it is a great way to see how your body is performing. Shanti
