Training Day 1

What the hell was I thinking! I am instructed that as a beginner I only have to run 60 seconds then walk 60 seconds for 30 minutes. As the treadmill is turning I am not sure I can run 60 seconds! My two year old is hanging his arms over the safety gate that surrounds the treadmill and staring in wonder. I begin to question if I should have taught him how to dial 911! Then he states, "Mommy you make the floor shake". Not the words of inspiration I was hoping for on training day 1.
