MY 4 YEAR OLD HID MY KEY

Collin my 4 year old hid my key to my treadmill. I haven't been able to find it or talk it out of him. So i haven't been able to run on the treadmill. My diet has been doing good. But exercising not so much, I am determined to find it today. I need to keep running then I would lose so much more weight and inch's. My real goal is to get into a smaller size and running on know will help out a great deal.
